Expanding universe of “prior art”: Patent applications will be more vulnerable to attack if filed after March 16, 2013

HR1249U.S. patent law is scheduled to soon experience major changes under the America Invents Act (AIA) that will make it harder to get a patent granted and that will make it easier to challenge an issued patent.  Therefore, if contemplating filing a patent application in the near future, it’s wise for applicants to do so before March 16, 2013, the day these changes take effect.

One major change is that the “prior art” universe is expanding on March 16, 2013.  “Prior art” is the term used for references or activities that can be cited against the patentability of a patent application or the validity of an issued patent.  Under current law, for a sale, offer for sale, or public use of a product to qualify as “prior art,” this activity had to (i) occur in the U.S. and (ii) be earlier than one year before the patent application’s filing date.  Under the new law, being on sale or in public use anywhere in the world can be cited.

In addition, under current law, for a foreign patent application to qualify as “prior art” against your U.S. patent application, it has to satisfy at least one of the following conditions:

  1. published before your conception date,
  2. published more than one year before your filing date, or
  3. filed before your conception date as an international patent application under the Patent Cooperation Treaty (“a PCT application”), that was published in English, designated the U.S., and resulted in a granted patent.

Under the new law, conditions (1) and (3) of the current law disappear since the conception date no longer matters (as discussed below).  Condition (2) of the current law excludes all foreign patent applications that published less than one year before your filing date, but under the new law, condition (2) is modified to only exclude foreign patent applications by the inventors (or obtained from the inventors) that are published less than one year before your filing date. 

A second major change in U.S. patent law, receiving the bulk of the buzz regarding the new law, is that the U.S. is changing from a “first to invent” standard to a “first to file” standard.  It’s always been beneficial to file patent applications as soon as possible, but under the old “first to invent” standard, even if you filed your patent application after someone else did for the same invention, you could be awarded the patent instead of them by proving that you were the “first to invent,” i.e., you invented the claimed invention before they did.  However, under the new “first to file” standard, the first party filing their patent application is awarded the patent, regardless of who was the “first to invent.”  

(Rigorously speaking, the new law is actually a ”first inventor to file” standard, since it prevents someone from obtaining the invention from the inventors, and then racing to the patent office to file an application first for something this someone didn’t actually invent.)

It’s rare that two entities separately conceive and file patent applications for the same invention.  But this change to a “first to file” standard makes an important contribution that further expands the “prior art” universe.  Under the current “first to invent” standard, the date that you conceived of the claimed invention could be used to exclude a certain category of references that were available to the public before your filing date from being considered “prior art” against your patent application.  But under the “first to file” standard, applicants can no longer rely on their earlier date of conceiving the claimed invention to overcome any cited references.  In other words, conception date will no longer matter; only the application’s filing date will control.

Besides expanding the “prior art” universe, the new law also introduces a new “post-grant review” (PGR) mechanism for challenging the validity of U.S. patents within nine months of issuance before the Patent Trial and Appeal Board.  This mechanism became available to challenge so-called “business method” patents in September 2012, but on March 16, 2013, it will be available to challenge all U.S. patents with filing dates after this date.  In conjunction with the other mechanisms for challenging issued patents (e.g., ex parte reexamination and inter partes review), each with its own requirements and pros and cons, PGR opens up a new way for competitors to invalidate your patent.

Finally, the new law includes language that has not yet been interpreted by the federal courts, so the full effects of the new law are uncertain at present. 

For one example, with regard to the activities anywhere in the world being “prior art,” as discussed above, the new law states that the application can be rejected if the claimed invention is ”in public use, on sale, or otherwise available to the public” before the application’s filing date.  So does “otherwise available to the public” mean that a private sale of the invention would not qualify as “prior art” under the new law?  Under existing law, any sale or offer for sale in the U.S.would qualify as “prior art,” public or private.  Until the courts weigh in, it’s probably prudent to make the conservative assumption that any sales or offers for sale, public or private, would qualify as “prior art” and to strive to not enter into such activity unless a patent application is already on file.

For another example, the new law excludes “disclosures” made by the inventors (or obtained from the inventors) within one year before the application’s filing date from being considered as “prior art” against the application.  But are being ”on sale” or “in public use” considered to be ”disclosures” under the new law?  Under existing law, sales, offers for sale, and public uses are excluded from being “prior art” if within one year before the application’s filing date.  Here, until the courts weigh in, the conservative assumption to make is that this one-year grace period does not apply to these activities.  In other words, don’t do anything that might be considered to be a disclosure of the invention until you first have a patent application filed.

In summary, under the new regime of the AIA, patent applications filed after March 16, 2013 will have to overcome a larger universe of “prior art” references to be granted as a U.S. patent, there will be more options for competitors to challenge the validity of such patents, and there will be uncertainty in how the law applies to various situations.  Therefore, potential applicants should consider filing their patent applications before March 16, 2013, to avoid this new regime.

Paying a Premium: How to get a U.S. patent within one year

One of the most common gripes I hear about the patent process cites the excessively long time it takes between filing a patent application and getting the patent to issue.  For example, the latest statistics out of the USPTO show that for applications in the “Semiconductor, Electrical, Optical Systems & Components” category, it takes an average of 26.5 months after filing to get the first office action, and an average of 29.3 months for the patent to issue.  This technical category is actually one of the fastest, with ”Computer Networks, Multiplex Communication, Video Distribution, and Security” being the worst, with averages of 33.6 and 40.7 months, respectively.

The USPTO has been working to reduce this pendency time, and has announced its “2010-2015 Strategic Plan” that sets the goal of reducing the average total pendency of patent applications to 20 months by 2015.  Much of this effort is focused on the USPTO’s internal processes, and as a patent practitioner, I support these improvements.

But even beyond these improvements, there are ways that applicants can help themselves and position their applications to be among the fastest through the USPTO.  In my opinion, these measures are currently underused in general, and many companies, especially those in high-tech fields such as photonics and optics, can reap the substantial benefit of getting a patent in hand within one to one-and-one-half years.  In this blogpost (and following blogposts), I’ll explain some of the measures that can be used by applicants to expedite their applications through the USPTO.

Paying a Premium: The easiest and most potent way to get a U.S. patent to issue within one year is to use the USPTO’s newly-enacted “Prioritized Patent Examination Program” (also known as “Track I”) which started this past September as part of the “America Invents Act” (“AIA”).  Under this “fast track” program, an applicant can file a petition and pay an extra fee to the USPTO ($2,400 for small entities, $4,800 for large entities).  Upon approval of the petition (99% approval rate so far), the USPTO will expedite the application with the goal of having the patent processed to completion within 12 months. 

The early results from the program are very attractive:

  • Over half of the approximately 1,200 “fast-track” requests filed since the program began in September 2011 have already received their first office action, with an average time of 66.4 days after filing.
  • There have already been 23 allowances under the program, with the average time to allowance being 39.2 days from petition approval.  The first allowance came 103 days after the application was filed (U.S. Pat. No. 8,094,942 issued to Google).
  • The program was initially open to only newly-filed applications.  However, it has recently been expanded to include pending applications for which a “Request for Continued Examination” has been filed.

Acceptance into the program is not a guarantee of issuance.  The USPTO will still apply the same standards of patentability as are used for all other applications.  For example, some applications in the program have already received their final rejections, with the average being 34.3 days measured from approval of the petition to enter the program.  In addition, the program is limited to accept only 10,000 applications during the fiscal year. 

For a company planning on going through the due diligence accompanying funding events or acquisition in the foreseeable future, it can make sense to improve its IP portfolio in the eyes of the VCs or acquisition entity by getting patents in hand sooner rather than later using the “Prioritized Patent Examination Program.”

Fiber MOPA without stimulated Brillouin scattering; Mobius Photonics, Inc.; U.S. Pat. No. 8,009,705

U.S. Patent No. 8,009,705, issued on August 30, 2011 to Mobius Photonics, Inc. of Santa Clara, CA, discloses a fiber-based master oscillator power amplifier (MOPA) that generates optical pulses using a photonic crystal fiber.

    

According to the ’705 patent, conventional high-power laser sources (e.g., for laser micromachining) utilizing a MOPA system cannot generate the high-power laser pulses with pulse widths longer than about 1.7 nanoseconds.  Among the phenomena that can limit the pulse width is stimulated Brillouin scattering (SBS), in which a significant portion of the amplified light is converted to Brillouin-scattered light having a lower frequency than the incident light.  In the system disclosed by the ’705 patent, seed pulses (e.g., from a distributed-feedback or distributed Bragg-reflector type semiconductor diode laser)  are amplified by a photonic crystal fiber amplifier which generates pulses having a peak power greater than 1 kilowatt, but less than the threshold power needed to induce stimulated Brillouin scattering.  This threshold can be increased by frequency chirping the seed pulses. 

According to its website, Mobius Photonics was founded in 2005 and “develops innovative, fast-pulse (from 100′s of picoseconds to 10′s of nanoseconds), fiber-based laser sources for the scientific and industrial markets.”  According to the USPTO database, the ’705 patent is Mobius’ fourth U.S. patent, and its first in 2011.

During prosecution of the ’705 patent, the USPTO rejected the pending claims, citing various prior art references.  One of these rejections cited an earlier-filed application owned by Mobius (which resulted in U.S. Pat. No. 7,529,281) under 35 U.S.C. § 102(e) of the patent law. 

Section 102(e) states that a claim should be rejected if it is anticipated by a patent granted on an application “by another” filed in the US “before the invention by the applicant.”  Under this provision of the patent laws, an applicant’s own work cannot be used against the applicant.  Another provision of the patent laws (§ 102(b)) does allow a public disclosure of applicant’s own work to be used against the applicant if the disclosure occurred more than one year before the priority date, but this condition did not arise in this case.

Under current US law, the applicant is the group of named inventors, not the owner of the application.  For example, although Mobius owns both applications, the applicant for the ’705 patent (i.e., the two inventors) is different from the applicant for the ’281 patent (the same two inventors, plus two other inventors).  On its face, since the inventorship is not identical, the ’281 patent satisfies the “by another” requirement of § 102(e).

However, Mobius was successful in proving to the USPTO’s satisfaction that the ’281 patent did not actually satisfy this requirement of § 102(e).   Mobius filed a declaration in which the two inventors common to both the ’281 patent and the ’705 patent asserted that the two of them, and not the other two listed inventors, were the true source of the relied-upon subject matter of the ’281 patent.  Thus, this material and the claims of the ’705 patent came from the identical group of individuals, so it is not “by another” and it cannot be used to reject the claims of the ’705 patent.  Once Mobius attended to the other rejections, using arguments and claim amendments, the USPTO fould the ’705 patent allowable.

Earlier this year, the “America Invents Act” was signed into law, which includes numerous changes to US patent law, most notably a change from a “first to invent” priority system to a “first inventor to file” priority system (effective for applications filed on or after March 16, 2013).  The act also includes a complete re-writing of § 102 (also effective on March 16, 2013), but which appears to preserve the concept of a disclosure of an inventor’s own work not being usable against him/her, as long as the disclosure occurred within one year of the priority date.
