Although the length of time that PTAB appeals are pending has only gone down slightly over the last three years, the number of new appeals has steadily declined.  This seems to be the case for both inter-partes and ex-parte appeals.

It’s not clear why that has happened.  One theory is that the relatively lower cost of IPRs and other appeals has made patent holders more likely to settle with a potential competitor – to avoid a relatively high chance of the patent rights being voided.

Provisional applications in the US only last one year.  If no utility or international application is filed during that one-year window, a provisional goes abandoned, and cannot be used to claim priority.  Sometimes the applicant is not ready to file a utility or international application during that window, and instead re-files the provisional. 

The problem is that if that re-filed provisional is filed while the earlier provisional is still pending, there is a chance that a priority claim to the re-filed provisional will fail in a subsequently national or regional phase application.  Article 4(c)(4) of the Paris Convention provides that any subsequently-filed priority application can only serve as the basis for priority over an earlier-filed priority application if several conditions are met, including that there are no remaining rights from that earlier-filed application when the subsequently-filed application is filed.  In the European Patent Office (EPO), for example, a request for re-establishment could be filed up to 2 months after the one-year window has passed for the earlier-filed provisional.  If such a request for re-establishment is granted, there would still be outstanding rights from that earlier-filed provisional, and priority to the subsequently-filed application would fail. 

Best practice then, is that if a re-filed provisional is used as priority for a PCT application, any earlier-filed but still pending provisional should be expressly abandoned before refiling the provisional.  Kudos to Terri Shieh-Newton, PhD of Mintz-Levin for pointing out this problem.


Patexia is a terrific resource for statistics regarding intellectual property.  Earlier this week Patexia reported that there has been a 20% drop in IPR (Inter-Partes Review) petitions since 2019.  Their 4th Annual IPR Intelligence Report, which can be purchased for $1495, breaks out IPRs handled by each law firm during the last five years, including a gauge of success rate. 

Fish IP has represented both petitioners and patent owners in over 10 post-grant proceedings before the Patent Trials and Appeals Board (“PTAB”), including both Inter Partes Reviews (“IPR”) and Covered Business Method (“CBM” reviews).  Fish IP has achieved over a 90% success rate before the PTAB, and 100% success rate on appeals to the Federal Circuit.   Fish IP’s work included winning one of the first ever CBM trials, and – at the time – one of only six (6) successful patent owner motions to amend (as cited by the U.S. Supreme Court). The technologies in Fish IP’s proceedings ranged from financial software to a variety of mechanical and electrical engineering inventions.  Fish IP’s work also resulted in several precedential opinions from the PTAB.


Fees are going up by an average of about 5%.  Basic out-of-pocket costs for filing a utility application will go up to $910 for a small entity, and half that for a micro-entity. Of course, additional charges will still apply for excessive number of claims and excessive number of pages.  The patent office is also continuing to disfavor multiple dependent claims, raising the base charge for such claims from $820 to $860. Continuing prosecution costs will also increase, for Continued Examinations (RCEs), extensions, and issue fees.  Interestingly, the patent office will begin applying a surcharge for applications filed in formats other than DOCX, but that surcharge will not take effect until Jan 1, 2022.  Current fees can be found on the USPTO website.

Standards Essential Patents

Standards Essential Patents (SEPs) claim inventions that must be complied with to satisfy a technical standard.  Think for example, MP3 music compression technology.  Given that essentially everyone needs to license patents covering aspects of the standard, it is critical that everyone has a reasonable opportunity to license the patent rights at a reasonable, non-discriminatory fee (so-call FRAND licenses).  See e.g., Wikipedia article.  Naturally, some bad actors try to circumvent that arrangement, by seeking excessive rates from potential licensees.  And that problem has historically been compounded by different rules in different jurisdictions.  In August 2020 the U.K. Supreme Court took a giant step towards international conformity by holding that English courts have the power to set global licensing rates for multinational patent portfolios under European telecom standards!

FRAND (Fair Reasonable And Non-Discriminatory licensing)

In May, the German Federal Court of Justice recently issued a landmark, 41-page decision that could well make Germany the “go-to” venue for patent owners in future FRAND licensing disputes.  In Sisvel v. Haier, the Court held that patent owners could satisfy FRAND requirements even if they provide different rates to competing licensees, at least when dealing with larger, multinational patent portfolios.  More information here.

Indian IP Office Extends Deadlines
