Design Patents

April 30, 2013

Utility patents get all of the publicity in when discussing innovation.  This could be changing with Apple’s $1.05 billion verdict against Samsung, which was based in large part on infringement of Apple’s design patents.

Another option that an inventor may want to consider is a design patent.  Utility patents cover structural and functional aspects of an invention, while design patents cover the asthetic features.

Design patents differ from utility patents in a number of basic ways.  A design patent is granted to cover the ornamental design of an object that has practical utility.  For example, a design patent may be obtained for a new shape of a beverage container, the particular shape and features of the tread of a shoe, computer icons, and other items that have practical utility.

A design patent is not permitted for something that exists for purely aesthetic reasons, such as a work of art.  A painting, sculpture, or other work of fine art would be protectable by copyright and possibly other intellectual property rights, but would not be eligible for design patent protection.

An invention may be entitled to both a utility patent and a design patent since a utility patent protects the structure of an article and the way it is used and works; a design patent protects the way an article looks.  If the design–the way the article looks–is dictated primarily by the article’s function, it would not properly be the subject of a design patent.  An example may be the shape of a gear that is designed primarily to fit with other gears and not for aesthetic purposes.

The requirements for obtaining a design patent are similar to that for utility patents.  The design must be novel and non-obvious; the examiner will perform a search of the prior art to be certain that the design meets these requirements.  Furthermore, the drawings must clearly show the features sought to be protected by patent.  The drawings will typically be more detailed than in a utility application as they will often show more views of the invention.  The drawings contitute the claims of the design patent.  Because they don’t require a detailed specification like a utility patent, design patents are also less costly to prepare and file.

Design patent protection lasts for 14 years (shortly to increase to 15 years) from the date the patent issues compared to 20 years from the earliest filing date for a utility patent.  No maintenance fees are required for design patents.

Another advantage of design patents over utility patents is that they seem to be much easier to obtain.  In recent years, design patents have had an allowance rate of about 90% over the last few years, compared to utility patent allowance rates of under 50%.  Over 80% of design patent applications are allowed without rejection; only 1.2% are rejected based on prior art with a larger number rejected on formality grounds.

In an era of increasing backlog and pendency of utility applications, more than half of design patents are pending for less than a year, with the average pendency being about 16 months.

For an invention where design and utility patent protection are both appropriate, I would not skip the utility patent.  An inventor should at least file a utility application for its broader scope of coverage and should also consider a design patent.  A design patent would provide some protection while waiting for a utility patent to issue.  They are also cheap since they don’t involve a great deal of preparation and prosecution.  Inventors should always consider whether their inventions are eligible for design and utility patent protection.

Be Certain to Rebut Examiner’s Statements During Prosecution

April 17, 2013

Yesterday, a divided panel of the Federal Circuit affirmed the district court’s narrow claim construction based on the applicant’s prosecution history disclaimer in Biogen IDEC v. GlaxoSmithKline.

Biogen obtained a patent that covered a method for treating patients with Chronic Lymphocytic Leukemia (CLL) by administering a therapeutically effective amount of anti-CD20 antibody.  Anti-CD20 antibodies are antigen proteins that are capable of being used in cancer treatment.  At issue in the case was the meaning of the term “anti-CD20 antibody.”

During prosecution of the patent, the examiner rejected the claims for lack of enablement.  The claims were not enabled under the broadest reasonable interpretation standard used by the PTO for “any and all anti-CD20 antibodies, no matter the specificity or affinity for the specific epitope on the circulating tumor cells.”  The examiner acknowledged that the specification did enable certain antibodies, such as RITUXAN® (rituximab), but was silent as to necessary specificity and affinity for other anti-CD20 antibodies.

The applicant responded that those of skill in the art would know that

even though antibodies directed to the same antigen might have different affinities and functional characteristics, one of skill in the art could readily identify an antibody that binds to CD20 with similar affinity and specificity as does RITUXAN® using techniques that are well known in the art. . . . With that knowledge in hand, the skilled artisan could readily produce anti-CD20 antibodies using similar techniques, and screen such antibodies for those having an affinity and functional activity similar to RITUXAN®.

The examiner then withdrew the enablement rejection and the claims were allowed.

GSK developed an anti-CD20 antibody with distinctly different characteristics from RITUXAN®.  Biogen sued GSK for infringement.

The district court construed the term “anti-CD20 antibody” to mean “rituximab and antibodies that bind to the same epitope of the CD20 antigen with similar affinity and specificity as rituximab.”  This construction was based on Biogen’s disclaimer during prosecution of the patent to overcome the examiner’s enablement rejection.  Biogen stipulated that, under this construction, GSK did not infringe the claims of the patent.

Federal Circuit

On appeal, Biogen argued for the ordinary and customary meaning of the anti-CD20 antibody claim term.  The court acknowledged that to overcome this heavy presumption of the ordinary meaning, a “clear and unmistakable disavowal” by the applicant during prosecution is required.  The majority ruled that the applicant did make such a disavowal in this case.

According to the court, rather than challenging the examiner’s understanding of the “anti-CD20 antibody” claim term, the applicant merely argued that the claims were enabled for anti-CD20 antibodies that are similar to RITUXAN®.  The applicant seemed to acquiesce to the examiner’s assertion that the claims were not enabled for other types of anti-CD20 antibodies.

Although Biogen argued that the applicant was discussing functional and affinity characteristics of anti-CD20 antibodies generally, and suggested that those skilled in the art would apply their understanding of the selection of such antibodies similar to the selection of RITUXAN®, the court instead held that the statement demonstrated a disavowal of claim scope of reasonable clarity and deliberateness.

This case is highly unusual in that prosecution history disclaimers are usually a result of the applicant’s statements during prosecution, not the examiner’s.  The court, however, was unconvinced.

This case deals not only with applicants letting stand an examiner’s narrow characterization of a claim term, but also their adoption of that characterization to overcome the examiner’s enablement rejection.

Judge Plager dissented from the majority opinion.  He argued that the give-and-take with the examiner is part of a negotiation with the applicant.  Such negotiation often results in ambiguous statements as in this case.  These less-than-clear statements should not be used against the applicant as they do not enhance the prosecution history’s notice function to the public.  Such is the case here.  Judge Plager would reverse and use the ordinary meaning of the term.

Lessons

It seems fairly clear that in this case Judge Plager is correct.  The record seems less than clear as to why the examiner withdrew the enablement rejection.  Was it because the applicant disclaimed certain claim scope that was considered non-enabled?  Was it because the examiner was convinced by the applicant’s argument that by demonstrating enablement for certain anti-CD20 antibodies that it was enabled for others as well?  This is definitely not a clear and unmistakable disavowal of claim scope.

The lesson, however, is that applicants should rebut all of the examiner’s statements in office actions with which he does not agree.  In this case, the applicant may believe that he did just that.  He presented an argument that overcame the examiner’s rejection.  This is a really tough opinion on this issue.

Earlier in my career, I worked with an attorney in the past who taught me to use language such as the following.

To avoid any unintended consequences to the contrary, the undersigned respectfully does not accept or acquiesce in any statement, argument, or description in the Office Action except as expressly stated herein.

While this language generally seems to be overkill, and seems to be merely boilerplate, it would (hopefully) avoid a situation such as in this case.

Provisional Patent Applications

April 15, 2013

A provisional patent application is a patent application that may be filed at the PTO that can be used to establish a filing date or date of invention.  The application expires 12 months from its filing date.  This means that, in order to claim the benefit of the provisional application filing date, a non-provisional or foreign patent application must be filed within that 12 month period.

There is no such thing as a “Provisional Patent”, although you may hear that term.  A provisional patent application does not give the inventor any rights to exclude, as an issued patent does.

The PTO does not examine provisional applications, but merely keeps them in its records.  Filing a provisional application does not get the invention examined any more quickly; in fact, the application does not go into the examination queue at all, so it actually takes longer from the initial filing date of the provisional application to begin examination than if a non-provisional application were filed initially.

The public does not get access to a provisional application unless and until a non-provisional application that claims the benefit of the provisional application filing date is published.  A provisional application can delay publication of the invention, even if the applicant will be filing outside the US.

Why File a Provisional Application?

The main reason is actually the delay.  The provisional application gives an additional 12 months to further develop the invention and to see if there is a market for the invention, and it can also delay prosecution costs associated with the application.

First, it often takes a long time to perfect a new product or process.  There are many details to work out and many improvements can be made in the early stages after the initial concept is completed.  To establish an early date of invention, a provisional application can be filed once the initial concept is completed, but prior to the perfection of the invention.  The 12 months before the non-provisional application must be filed can be an aid in this endeavor.  Additional provisional applications can be filed during the 12 month period to establish an invention date for any improvements.  Various strategies exist for which applications should be used for a priority claim.

Second, a provisional application delays some of the expenses associated with obtaining a patent.  For example, the filing fee for a provisional application is currently only $260/130/65 (large/small/micro entity), while the filing fee for a non-provisional application is $1600 ($730 for small entity filed electronically/$400 micro entity).  There are additional fees for excess claims, prosecution fees, and issue and publication fees.  It may be advantageous to delay these fees until it is determined that there is a market for the invention.  A provisional application gives the application 12 months to find investors, buyers, or licensees for the product or process.

A provisional application can be a good way to be certain that the inventor’s own activities will not be available for use as prior art.  If there is an imminent publication or product launch of the invention, say in a few days, and there is not time to prepare a complete and thorough application, a quick provisional can be helpful.  A complete non-provisional should be filed as soon as possible thereafter, it is not necessary and can be dangerous to wait the entire 12 months prior to doing so.

Now that the US has transitioned from a first-to-invent to a first-to-file regime, filing a provisional application may be even more important.  Given that the grace period is severely restricted and that you need to beat any other potential filers to the Patent Office, filing a provisional application and later following up with a non-provisional can be a great strategy.  If you need to publicly disclose your invention, file a provisional application for it first.

Is a Provisional Application Cheaper?

There are ads on Google for $99 or $149 provisional patents.  It can be cheap to file a quick application to protect against public disclosure as noted above.

Many people believe that filing a provisional application is a simple thing.  Some inventors will do it themselves, before going to a patent attorney for a non-provisional application a year later.  Others want their attorney to prepare a bargain application of maybe a few pages or so.  After all, provisional applications don’t even require claims.

Sometimes, it is necessary to file a quick and dirty provisional application, such as where there is going to be an imminent product release or publication that could create a bar to getting a patent in the future.  In general, however, it is not cheaper to prepare a provisional application than a non-provisional application.

In order for a later-filed non-provisional application to obtain the benefit of the filing date of a earlier provisional application, US patent law requires that the claims of the non-provisional application be supported by the provisional application.  What this means is that an applicant must include sufficient detail in the provisional application in order for it to do any good.  Otherwise, you are only entitled to the filing date of the non-provisional application.  In that case, the provisional was a waste of time and money and the delay in filing the non-provisional application may be detrimental to obtaining a patent for the invention.

Applicants should take the time and spend the money to have a good provisional application prepared that includes as much detail as is available at the time of filing the provisional application.

In summary, a few points are worth mentioning or repeating:

  • A provisional application can be a good idea to establish an early filing date and to give additional time to perfect the invention or work on improvements, as well as to determine whether there is a market for the product or process.
  • A provisional application can also be a good way to delay filing and prosecution costs until a later date.
  • A provisional application should not be filed until the invention includes sufficient details to reduce the invention to practice.
  • Provisional patent applications should include sufficient detail to support claims in a later-filed non-provisional application.
  • A provisional patent application permits the applicant to mark a product as “patent pending.”
  • A quick provisional application can be filed to protect against public disclosure provided that a complete non-provisional application is filed shortly thereafter.

IP in Employment Agreements

April 9, 2013

For a company with substantial intellectual property in hand and under development, it is important to have employment agreements for new employees that include clauses for dealing with intellectual property rights.

When hiring new employees, be certain to have IP disclosure and assignment clauses in employment agreements for all employees.  These clauses should require the new employee to promptly disclose new inventions or other intellectual property to the employer upon conception and to assign such inventions to the employer at that time.  Be certain that the agreement is clear that the employee has an obligation to assign new inventions to the new employer as a part of the employment.

Have all new employees sign such agreements prior to employment or at least on the first day.  Some states may require additional consideration once employment has already commenced for such clauses to be valid.

When preparing such agreements, keep in mind that certain words have specific definitions or understandings in patent law.  For example, ambiguity could arise as to whether the employee would “conceive” and “make” an invention.  Try to stick with the definitions that are common to patent law.  “Conception” refers to “formation in the mind of the inventor, of a definite and permanent idea of the complete and operative invention, as it is thereafter to be applied to practice.”  This is more than just a vague idea, it requires definite plans for how to implement the invention.  “Make” or “reduction to practice” refers to the act of actually making the invention work for its intended purpose.

Next, to avoid a dispute as to whether the employee developed the invention prior to employment, when executing the agreement, give the new employee the opportunity to indicate that he developed the invention prior to commencing employment.  Require that he prove this development by providing sufficient detail that he can’t later argue that vague statements constitute conception.  Unless the parties agree otherwise, the employee should retain all rights in inventions that he conceived or invented prior to commencing employment.  To reduce the chances of a dispute regarding this issue, try to get it out there early in the process rather than waiting until later.

Finally, use language that requires the employee to promptly disclose inventions to the company and to “hereby assign” all future inventions.  The assignment is not required later once the employment has ended and you need to chase the employee and potentially sue him.  Instead, make it effectual as soon as inventions are conceived.

Former employees are not always cooperative in the patent process for their former employers.  You should probably include language the grants the employer at least a partial power of attorney to execute documents on behalf of the former employee inventor in cases where that becomes necessary.

Searching for Prior Art

April 4, 2013

A question that is often asked by new inventors is:  should I do a prior art search before filing a patent application?  The answer, as in most areas of law and life in general, is that it depends.

For individual inventors and smaller companies including start-ups, in most circumstances, I would suggest that yes you should do a prior art search.  Many larger companies have a number of scientists and technologists who are familiar with the technology and what their competitors are doing.  They can also absorb the potential risks of not doing a prior art search.  Most small entities and start-ups do not and can not.

Many, if not most, new inventors are convinced that they are the only ones that have thought of the idea that they seek to patent.  They believe that they have had a flash of insight that no one else has had.  They may even do a bit of Internet research to convince themselves that they are in the clear and that there is no need to do a prior art search.  They are often surprised by the results when they do have a search conducted.

The risks of not doing a search are several.  First, and most importantly, if you plan to commercialize or market the invention as a product or service, you don’t want to get slapped with an infringement lawsuit right out of the gate.  These suits are extremely expensive even if you don’t get hit with a large damage award.  There is a risk that you will not be able to afford to defend such a suit and that all of your hard work in developing the invention, getting it through the prototype stage, and getting it to market would be wasted.  Usually, there is a significant monetary and time investment involved with these steps.  There is also a risk that a court could issue an injunction that would prohibit you from making, using, selling, or offering the invention for sale.

Second, conducting a prior art search prior to preparing a patent application may make prosecution of the application more efficient and cost-effective.  By knowing the closest prior art, the patent application and the claims may be prepared more strategically to take advantage of areas of patentability.  Claims may be prepared that get close to the prior art without encroaching on it.  It may be possible to develop arguments and strategies for convincing the patent examiner that the invention is non-obvious vis-a-vis the prior art.

You may find that the invention needs to be reconfigured to “design around” patents that are found.  This could add to the value of the invention and potentially give you a competitive advantage.  You may find, however, that someone else has a patent that directly prevents you from patenting your invention.  In such a case, you may determine whether to abandon your endeavor or seek to partner with or secure a license from the patent holder.

The main disadvantages of conducting a prior art search are that it will cost some money and that any material prior art that is uncovered must be disclosed to the Patent Office during prosecution of any patent application that is filed for your invention.  The cost is usually not significant in the overall scheme of bringing a new product or service to market and preparing and prosecuting a patent application.  In fact, a good prior art search can make these endeavors more efficient.  Most patent applicants are looking for strong patent protection in which case it is not a disadvantage to bring prior art to the patent examiner’s attention.  This will permit the patent to be “vetted” over that prior art.

Mechanics

A patent attorney can assist you in having a prior art search performed.  A brief written description and possibly a few drawings or sketches of the invention should be prepared.  This information is provided on a confidential basis to a professional patent search firm that will conduct the patent search.  These firms are usually located in Northern Virginia near the PTO and are staffed with engineers and scientists, at least some of whom may be former patent examiners.  The search firm provides the information to a person with skill in searching the subject matter of the invention who conducts the search.

A good “freedom to operate” and patentability search takes a couple of weeks to complete and usually costs less than $2,000, often less than $1,000.  For a “freedom to operate search,” the searchers will search that claims of US patents that are currently in effect.  For a patentability search, the searchers will also search for older US patents, foreign patents, and non-patent literature that may disclose the invention.

The results will typically include a stack of the closest 20-30 patents and other prior art references.  My practice is to provide these results to the inventor with instructions to review them in detail and to bring any that the inventor believes warrant further review by me to my attention, in any event the closest 3-4.  This saves on attorney time of having to review the entire stack.  The inventor is usually in the best position to determine any differences or similarities between the references and the invention.  At that point, we determine how best to proceed with the matter based on the search results.

One might reasonably ask why the inventor or the attorney cannot themselves conduct the prior art search on Google, the PTO website, or another search engine.  One answer is that it is far more efficient for these experts to perform the search than for the attorney to do so.  Their hourly rates are typically much less.  Second, I am always amazed that the professional searchers find prior art that I or the inventors have not been able to find.

In sum, I almost always advise a new inventor, small company, or start-up to have a prior art search done prior to marketing the invention or preparing a patent application.  In my opinion, the advantages of such a search far outweigh the risks or costs of doing so.

Patenting Your Invention Outside the US

March 27, 2013

A patent permits its owner to exclude others from making, using, selling, offering for sale, or importing the patented invention without his permission.  A patent is, however, unique to the country where it is granted.  Thus, if a patent owner does business in more than one country, it would be necessary to obtain a patent in each country to protect the invention.

Some countries have restrictions on what can be patented.  For example, some countries do not permit patenting software, business methods, drugs, or methods of treatment for humans.

PCT Applications

One way to obtain patent protection in multiple countries is to file an application under the Patent Cooperation Treaty (PCT).  A PCT application is an international application that is filed through the World Intellectual Property Office (WIPO), where an applicant can designate a large number of countries in which he desires to file his patent application.  Currently, 146 countries are members of the PCT.

A PCT application does not give the applicant an “international patent”, as all patents are national in nature (although certain organizations like the European Patent Office (EPO) issue a “European Patent” that must be registered in each member country where the applicant desires the patent to be in effect).  Instead, the PCT provides a mechanism that gives the applicant 30 or 31 months from the earliest filing date (the first filed patent application) to determine whether to file the patent application in various individual countries.  A PCT application can either be the first filed application for an invention or it must be filed within 12 months of the first filed application.

The PCT also provides an International Search Report and an examination, if desired, so that the applicant can get an early search performed to see if the invention is patentable.  The delay also permits the applicant to determine whether the invention is commercially valuable and whether it is worth spending the money to obtain a patent in each country.  While applicants may designate all 144 countries at the time of the PCT filing, they can decide later in which individual countries they would like to pursue patent protection.

A PCT application can also save money on translation costs early in the process.  While most individual countries require patent applications to be filed in the native language of that country, PCT applications permit applicants to delay the cost of translating the application into the various languages.

Once the 30 or 31 month period from the first filing date elapses, a PCT applicant must “enter the national stage” in each country where a patent is desired.  Otherwise, the application is abandoned and patent protection cannot be obtained.  It is at this stage where translations must be obtained and filing costs for the various countries must be paid.

Each country usually requires that the applicant work through an attorney or patent agent who is registered to practice before that country’s patent office.  Thus, to obtain a patent in Brazil, the applicant must work with a Brazilian patent attorney or agent.  These attorneys and agents charge fees for their services, further adding to the costs of obtaining patent protection in various countries.

If the PCT procedure is not utilized, applicants must file in each individual country within a year of the filing date of the first filed application.  The translation, filing, and agent costs are due at that time.  A primary advantage of the PCT is the 18 to 19 month delay for these costs.

While 146 countries are currently members of the PCT, there are several significant countries that are not members; these include Argentina, Paraguay, Uruguay, Venezuela, Taiwan, and the Middle East.  To obtain patents in these countries, a patent application must be filed in each within 12 months of the first filed application.

Patent Prosecution Highway

The United States PTO has entered into an agreement with 21 other patent offices called the Patent Prosecution Highway.  Under this program, once a patent claim is found to be allowable by the patent office where the application was first filed, the applicant may request that other patent offices fast track examination of the application.  This is a type of work-sharing program intended to cut reduce redundancy in examination.

Beware of Public Disclosure

March 18, 2013

The United States patent system is now officially First-to-File.

A new website was brought to my attention of the weekend:  First to Disclose.  The website indicates that it is a “community-powered” site that was created by members of the Brooklyn Law Incubator & Policy Clinic at Brooklyn Law School.  The purpose of the website is stated as follows:

[to] provide[] inventors of all kinds an easy-to-use, fast and effective method by which to publicly disclose their inventions. Under certain circumstances, such disclosures can help secure the inventor’s patent rights.

The site suggests that such disclosure will keep larger inventors or companies from winning the race to the Patent Office by permitting smaller inventors to disclose their inventions on the site.  This disclosure will even start the one year grace period permitted under US law.

As I have previously warned, DO NOT RELY ON THE PUBLIC DISCLOSURE PROVISIONS OF THE AIA.  If you are merely trying to keep another party from getting a patent, then by all means disclose your invention.  If you want to get your own patent, there are simply too many risks associated with public disclosure prior to filing a patent application.

Foreign rights may be irrevocably lost.  This is not a change under the AIA, but should continue to be a significant consideration.  Public disclosure does NOT protect obvious variants of the invention.  If a third party files or discloses an obvious variant of your invention before you file your application, you will not be able to get a patent on the invention.  This point can hardly be stressed enough.

The best advice I can give for the new regime is:  file early and file often.

Examiner Interviews

March 7, 2013

Oral communication is often more effective than written communication.

Once I’ve been through a round of written responses with a patent examiner, if I feel that the examiner is not being receptive to my position, I will conduct an interview with the examiner.  Often, the examiner will indicate that he or she had not fully grasped the position before and now better understands the distinctions between the claimed invention and the prior art.  Even in cases where I don’t get the examiner to agree with me, we usually understand each other’s position better which enables me to better advise my client on how to proceed with the case.

It is often easy for an examiner to cut-and-paste language from previous office actions when responding to an applicant’s amendment.  Sometimes this is because the examiner doesn’t fully appreciate the applicant’s position, sometimes this is because the applicant and examiner are talking past each other.  An interview can often resolve these issues as the examiner must listen and consider the applicant’s position without resorting to cut-and-paste.

This isn’t to say that all interviews are successful.  Many examiners are not used to oral communication and will be non-committal.  This is especially true for junior examiners.  Junior examiners do not have authority to allow claims without review by a senior examiner or supervisor.  Thus, examiner interviews with junior examiners require a senior examiner with such authority to also be present.  The problem is that the senior examiner has his or her own docket and often is not familiar with the application and issues or is not prepared for the interview.  Such interviews can be frustrating and maybe even unhelpful.  And, many junior examiners are very reluctant to allow patents.

In any event, even if the interview does not result in allowance of the claims, I have more information about the application and the examiner’s position than I did prior to the interview.  I can advise my client that the examiner will not be persuaded.  Perhaps we are more likely to get a positive result through appeal rather than another round of responses.

Interviews are not a way to avoid making comments on the record that become part of the prosecution file.  If there is an outstanding office action, most examiners will require the applicant to send in a proposed amendment or set of arguments that will become a part of the record.  This can sometimes be avoided if the interview is conducted after a response has been filed.  After the interview, a written summary is prepared by both the examiner and the applicant that becomes part of the file.

Nonetheless, if I determine during an interview that a particular argument is clearly not going to persuade the examiner, and I don’t think the argument is vital to the case, I may omit it from my next response, thereby keeping it out of the record.

What Grace Period? Another Reason to File by March 16

February 25, 2013

The deadline for the transition of the US patent system from first-to-invent to first-to-file is fast approaching.  This change is significant and will result in applicants not being permitted to swear behind or prove prior invention of prior art references cited against applications filed after March 16 with claims that don’t have support in an earlier application.

There is, however, another significant reason to file by March 16.  The grace period is being significantly curtailed.

In the US, applicants have typically had a year to file a patent application after first public use or sale.  They could also pre-date prior art used in obviousness rejections that relied on prior art dated within a year of their application’s filing date.  This is changing.

Disclosure v. Public Use or Sale

While the PTO and a number of others argue that applicants will retain the ability to publicly use or disclose their inventions or offer them for sale for a year prior to filing a patent application, until the courts (read:  Federal Circuit) rule on the difference between a disclosure and a public use or sale, it would be risky for applicants to rely on the grace period.  The new law seems to literally protect disclosures, but not public uses or sales.  The courts (including the Supreme Court) have previously ruled that there is a difference between these activities.

Third Party Disclosures/Derivations

Perhaps just as importantly, the PTO has issued guidelines that indicate that there is no grace period for third party disclosures that pre-date an application’s filing that are obvious variants of the claimed invention.  There are several implications of this issue.

First, as seems to be intended by Congress, applicants cannot file patent applications that are obvious variations of inventions on which third parties have already filed.  Under current law (pre-March 16), if the applicant could prove an earlier invention date, it does not matter if the invention is obvious in light of the third party’s prior filing.

Second, this is a significant limitation of the grace period.  Under the letter of the new law, applicants can still publicly disclose their inventions and then file an application within a year.  Their own disclosures are not prior art.  If a third party sees that disclosure, however, and files a patent application that is not exactly what was disclosed by the applicant, but is instead an obvious variation of that disclosure, there is no grace period for the third party’s filing.  The applicant’s claims will be rejected as being obvious over the third party’s earlier filing.

It does not matter whether the third party “derived” the invention from the inventor or not.  Derivation protection only applies for identical disclosures.

What to Do

Until this situation is resolved and clarified (and perhaps even after depending on the results), applicants would do well to assume there is no longer an effective grace period in the US.  They should at least file a provisional application prior to any public use, sale, or disclosure.

HT:  Hal Wegner has been writing on this issue.

First-to-File Takes Effect March 16

February 1, 2013

The U.S. patent system transitions from a first-to-invent to a first-to file regime on MARCH 16, 2013.  For patent applications filed after that date that include claims that do not have priority to an application filed prior to that date, inventors will no longer be able to rely on earlier inventive activity to pre-date prior art.  If you have been working on an invention for a year and someone else has been working on it for a week, if that person files an application one day before you, after March 16, 2013 you cannot get a patent.

During the next six weeks, inventors should file applications for inventions they might otherwise feel are not ready for patenting.  This is good practice simply to be the magic date.  This is even important if you have pending applications for which you wish to add new claims that are not supported by an earlier application (CIP), as these will be examined under the first-to-file rules.

After March 16, 2013, inventors should file applications early and frequently during the invention process so that they do not lose the race to the patent office.  If a competitor files first, even by one day, there will be no patent for you.  Each time there is a significant improvement to the invention, a new application should be filed to prevent competitors from winning the race on the improvement as well.

CONSIDER FILING MULTIPLE PROVISIONAL APPLICATIONS

Inventors will often file a quick provisional application before a public disclosure and then wait a year to file a full non-provisional application that includes sufficient detail to warrant a patent.  Under the first-to-file system, if the first provisional is not adequately supported and enabled, an intervening filing by a competitor may trump the first provisional.  That first provisional still has merit, but inventors should consider filing additional provisional applications as details of the invention are developed to prevent the harm from intervening applications.  Applicants will no longer be able to rely on inventive activity to pre-date prior art.

RELY ON THE DISCLOSURE PROVISION WITH CAUTION

The new provisions seem to include a grace period once an inventor discloses the invention as long as an application is filed within one year of that disclosure.  Outside of the potential loss of foreign patent rights, applicants should also be aware that competitors may see the disclosure and develop alternative solutions to the problem the invention solves.  They could create prior art that may render the invention obvious.
