After Weber v. Provisur, Confidentiality Provisions May Not Be Sufficient to Protect Your Documents from Being Prior Art

On February 8, 2024, the U.S. Court of Appeals for the Federal Circuit issued a precedential decision in Weber, Inc. v. Provisur Technologies, Inc., reversing the finding of the Patent Trial and Appeal Board (PTAB) that certain operating manuals with limited dissemination and confidentiality restrictions did not qualify as prior art. The Federal Circuit’s decision concluded that the Board misapplied the analysis for meeting the public accessibility standard for a printed publication to qualify as prior art.

Federal Circuit Says Narrowing Limitation Does Not Create a Contradiction Leading to Indefiniteness

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision today reversing the Western District of Texas district court’s indefiniteness analysis and explaining that it improperly found a contradiction between two claim limitations to arrive at its indefiniteness holding. Amperex Technology Limited filed an action seeking declaratory judgment of noninfringement and challenged the validity of certain claims of Maxell, Ltd.’s U.S. Patent No. 9,077,035 for a rechargeable lithium battery and Maxell asserted infringement of the patent in a separate action. The two actions were consolidated in the Western District of Texas and the court ultimately held that two of the “wherein” clauses of the sole independent claim 1 of the ‘035 patent contradicted one another.

CAFC: PHOSITA Can Bridge Gaps with Reasonable Success Under Result-Effective Variable Doctrine

On March 5, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision in Pfizer Inc. v. Sanofi Pasteur Inc. affirming lower rulings by the Patent Trial and Appeal Board (PTAB) that invalidated Pfizer’s patent claims and denied motions to amend (MTA). Although the Federal Circuit vacated the PTAB’s MTA denials with respect to two patent claims, the ruling adds new contours to the appellate court’s case law on obviousness in ways that could affect companies that are patenting chemical inventions with claimed numerical ranges.

CAFC Partially Reverses Noninfringement Judgment But Scraps IBM Web Advertising Claims as Ineligible

The U.S. Court of Appeals for the Federal Circuit (CAFC) in a precedential decision today mostly upheld a district court ruling that found Chewy, Inc. did not infringe several claims of one IBM web advertising patent and that granted summary judgment of patent ineligibility on certain claims of another. However, the decision, authored by Chief Judge Kimberly Moore, reversed the district court’s finding of noninfringement on one of the five asserted claims of one patent, remanding the case for further proceedings on that issue.

UK Decision Provides Guidance on Takedown Notices and Unjustified Threats

A large number of businesses trade through online platforms and marketplaces such as Amazon and eBay. Consumers may believe that because goods are listed on a well-known trusted platform, they are authentic, and the sellers have been approved in some way by the service provider. Unfortunately, as too many business owners are aware, e-commerce platforms offer counterfeiters and infringers a relatively easy way of offering their infringing goods for sale. A balance must be struck between forcing online marketplace providers to police intellectual property disputes themselves and allowing businesses to protect their intellectual property rights effectively when they are being exploited via online platforms.

Rader’s Ruminations – Patent Eligibility, Part 1: The Judge-Made ‘Exceptions’ are Both Unnecessary and Misconstrued

In supreme irony, the U.S. Supreme Court lists the three exceptions to statutory patent eligibility in Chakrabarty, Diamond v. Chakrabarty, 447 U.S. 303 (1980) — the case most famous for the observation that Thomas Jefferson’s statutory language from the 1793 Act (still in place today) covers “anything under the sun made by man.” Id. at 309. While construing Jefferson’s “broad” statutory language in 35 U.S.C. 101 with “wide scope,” the Court noted: “The laws of nature, physical phenomena, and abstract ideas have been held not patentable.” Id. The Court tries to support this listing with a string citation to several cases — each standing for something different than an exception from statutory language. Still, to ensure clarity, the Court gives examples: “a new mineral discovered in the earth or a new plant found in the wild is not patentable subject matter.” Likewise, Einstein could not patent his celebrated law that E=mc2, nor could Newton have patented the law of gravity.”  Id. So far so good, but this classic example of the Court trying to sound informed and competent out of its comfort zone reemerges 30 years later to replace (and effectively overrule) the statutory rule that governed for over 200 years and remains in Title 35.
