CRU Faster Than Before AIA, Provides Options for Patent Owners

Patent reexamination filings have fallen 86% since 2012.  With the elimination of the popular inter partes patent reexamination option in 2012, an overall decrease was certainly expected.  However, ex parte reexamination filings continue to drop every year.  Only 191 ex parte reexamination requests were filed in 2017.  This was the lowest number of ex parte reexamination filings since the mid-1990s.  While an ex parte patent challenge is far less appealing to a patent challenger than a contested proceeding (AIA trial proceeding), and this factor has undoubtedly contributed to the decreasing numbers, patent reexamination and other post-grant proceedings of the Central Reexamination Unit (CRU) still provide unique rehabilitation opportunities for patent owners.Continue Reading Thwart PTAB Attacks With These USPTO Post-Grant Options

Long Delayed Fee Increase Hits January 16th

Section 10 of the Leahy‐Smith America Invents Act (AIA) authorizes the United States Patent and Trademark Office (USPTO) to, in part, “set or adjust by rule any fee established, authorized, or charged” under Title 35 of the United States Code. At the close of 2016, a Notice of Proposed Rule Making (NPRM) issued requesting comments from the public on proposed fee increases for post-grant patent proceedings, including AIA trials. A Final Rule Notice issued today setting significant increases to take effect on January 16th 2018 for AIA Trial Proceedings.

Article III Standing Only Necessary for Party Invoking Authority of Federal Courts

Last week, I analyzed the government’s arguments supporting Article III standing for intervenors in Knowles Electronics v. Matal. In that case, the panel questioned whether the government had Article III standing to intervene in a case where the original appellee dropped out. As to the arguments presented by the government, I explained that I found the most compelling argument to be that the agency can piggyback off of the Article III standing of the appellant as the standing inquiry is properly directed at those who invoke the court’s jurisdiction. 

Yesterday, two of the three judges (Newman, Clevenger) on the Knowles panel agreed with the above “piggyback” argument in Personal Audio, LLC v. Electronic Frontier Foundation.

Moving Forward on Indefinite Claims Could Haunt Petitioners

Often times when preparing an Inter Partes Review (IPR) petition, a claim is encountered that may be of an indeterminate scope under 35 U.S.C. 112. As indefiniteness issues are not considered in IPR, the question then becomes: Should the broadest of the possible competing construction for the claim term be proposed in order to get an IPR instituted on the claim? Or, should the petitioner avoid proposing a construction for an indefinite term to reserve rights for a later, district court challenge?  Of course, holding back claims for a later district court proceeding is typically disfavored given the entire point of IPR, in most cases, is to avoid the expense of district court litigation.  For that reason, most petitioners forge ahead to attack the indefinite claim.

As explained by the Federal Circuit this week in Sonix Technology Co., Ltd. V. Pubs. Int’l Ltd. et al., (here), Petitioners would be wise to note the 112 issue in their petitions.

PTAB Trial Not Necessarily Constrained to Petition Grounds

Patentees often amplify relatively insignificant technical differences between a patent claim and the prior art in district court to great success. Such strategies often fall flat in front of the USPTO where the technical expertise of the agency can expose such distinctions as inconsequential (inherent), or obvious — usually.

For example, in patent reexamination, examiners adopt and/or modify challenges to suit their technical understanding. Later, on appeal, judges of the Patent Trial & Appeal Board (PTAB) may issue new rejections where a trivial patent claim difference is known, or suggested by the art as obvious. More recently, however, the same PTAB judges reviewing AIA trial petitions often times take a hyper-technical view of proposed grounds of unpatentability. That is, judges of the trial section often feel constrained to the grounds presented in a petition even though an argued “distinction” over the proposed grounds is a well-known, trivial feature in the art.

Today, the Federal Circuit reiterated that the PTAB is not so constrained in dealing with AIA trial petitions.

Heightened Written Description Requirement for Negative Claim Limitations?

Negative patent claim limitations were once disfavored by the USPTO.  This is because defining claim scope by exclusion was considered less precise relative to more traditional, positive claim scope recitations.  Over the years, the USPTO has been guided to accept negative limitations as in some cases it may be the only way to adequately claim a given invention.  Yet, in assessing written description support for such claim features, the USPTO explains that “the mere absence of a positive recitation in a patent specification is not a basis for exclusion consistent with written description requirements.” MPEP 2173.05(i) 

In some cases, examiners have been known to require explicit support for a negative claim limitation. The degree of specification support necessary to support a negative claim limitation was analyzed last week by the Federal Circuit.

USPTO Releases Petition Timelines

The Office of Petitions has launched a new USPTO Patents Petitions Timeline that provides information on petition types that can be filed throughout each stage of the patent prosecution, and reexamination process. For each petition type, users can easily access information on average pendency over the past 12 months of decided petitions, the deciding office, petition grant rates, and link to specific sections of the Manual of Patent Examining Procedure (MPEP) or other parts of the USPTO website that relate to each petition type. (here)

Given the pro forma nature of many prosecution related petitions, of most interest are the more unusual filings, such as petitions to revive abandoned applications.

Of perhaps the greatest interest is the pendency information pertaining to petitions filed during patent reexamination. I have often referred to this practice as the “black arts” as such practice is fraught with uncertainty, and pendency can be quite significant.
