Mar. 6, 2024), the Federal Circuit reaffirms that a patent claim that includes narrowing limitations requiring only some elements of a Markush group recited in the same claim are not indefinite under Section 112 so long as the claim, when read as a whole, is internally consistent and supported by the specification.Continue Reading Federal Circuit Finds that a Narrowing Claim Limitation that Expressly Requires Optional Elements of a Markush Group from the Same Claim is Neither Contradictory Nor Indefinite

The Federal Circuit held that patent claims directed to storing and providing medical images over the web as “virtual views” were invalid under 35 U.S.C. § 101 because they involved nothing more than “converting data and using computers to collect, manipulate, and display the data,” and the amended complaint failed to plausibly allege that creating “virtual views” on the fly involved unconventional technology or a concrete application that would transform the abstract idea to significantly more.Continue Reading Federal Circuit Affirms Invalidation of Patents Manipulating Medical Imaging Data as Abstract

In CyWee Group LTD. V. ZTE (USA), Inc., No. 21-1855 (Fed. Cir. 2024), ZTE filed an IPR petition against U.S. Patent No. 8,441,438 (the ’438 patent) owned by CyWee, which the Patent Trial and Appeals Board (“the Board”) instituted. LG later filed a separate IPR petition also challenging the ’438 patent and moved to join ZTE’s IPR. LG acknowledged that its IPR petition was untimely under 35 U.S.C. § 315(b) because CyWee sued LG more than a year before LG filed its petition. LG premised its request for joinder on several limitations, the most relevant of which was that LG would act only as a passive understudy and not assume an active role in the IPR unless ZTE ceased to participate in the instituted IPR.Continue Reading Navigating Revised Motions to Amend in Inter Partes Review as a Non-active, Joined Party

The USPTO issued guidance on February 6, 2024 that clarified existing rules and policies and discussed how to apply them when AI is used in the drafting of submissions to the Patent Trial and Appeal Board (PTAB) and Trademark Trial and Appeal Board (TTAB). As a follow up, the USPTO has now published additional guidance in the Federal Register on some important issues that patent and trademark professionals, innovators, and entrepreneurs must navigate while using artificial intelligence (AI) in matters before the USPTO. The guidance recognizes that practitioners use AI to prepare and prosecute patent and trademark applications. It reminds individuals involved in proceedings before the USPTO of the pertinent rules and policies, identifies some risks associated with the use of AI, and provides suggestions to mitigate those risks. It states that while the USPTO is committed to maximizing AI’s benefits, the USPTO recognizes the need, through technical mitigations and human governance, to cabin the risks arising from the use of AI in practice before the USPTO. The USPTO has determined that existing rules protect the USPTO’s ecosystem against such potential perils and thus no new rules are currently being proposed.Continue Reading USPTO Issues Additional Guidance on Use of AI Tools in Connection with USPTO Matters
