In 2024, the Federal Circuit issued eighteen opinions labeled “precedential” that were related to patent law. Quotations below omit citations and internal quotations. Here is a break-down:
Cytiva Bioprocess R&D AB v. JSR Corp.: Non-obviousness of novel compounds
Holdings:
Palo Alto Networks, Inc. v. Centripetal Networks, LLC et al.: Motivation to combine (Patent challenger appeals from unsuccessful IPR.)
Pfizer Inc. v. Sanofi Pasteur Inc.: Optimization of result-effective variables (Patent owner Pfizer challenges IPR holding of invalidity.)
Holdings:
Virtek Vision Internat'l ULC v. Assembly Guidance Systems, Inc.: Motivation (Patent owner Virtek and patent challenger Aligned Vision cross-appeals IPR findings of a subset of challenged claims invalid.)
Holdings:
Sanho Corp. v. Kaijet Tech. Int'l Ltd.: Excluding prior art under § 102(b)(2)(B) (Patent owner Sanho appeals invalidity finding by PTAB.)
35 U.S.C. § 102(b)(2): A disclosure shall not be prior art to a claimed invention under subsection (a)(2) if–
(B) the subject matter disclosed had, before such subject matter was effectively filed under subsection (a)(2), been publicly disclosed by the inventor or a joint inventor or another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor.
Holdings:
Weber v. Provisur Tech.: Printed publication requirement. (Patent challenger Weber appeals PTAB holding that Provisur's patents were not invalid.)
Holdings:
LKQ Corp. v. GM Global Tech. Operations, LLC: Design Patent Nonobviousness (Patent challenger LKQ appeals PTAB decision upholding GM's design patent on a vehicle front fender.)
Holdings: “We conclude that the Rosen-Durling test requirements—that (1) the primary reference be “basically the same” as the challenged design claim; and (2) any secondary references be “so related” to the primary reference that features in one would suggest application of those features to the other—are improperly rigid. The statutory rubric along with Supreme Court precedent including Whitman Saddle, Graham, and KSR, all suggest a more flexible approach than the Rosen-Durling test when determining obviousness.”
IOENGINE, LLC v. Ingenico Inc.: Printed matter doctrine (Fed. Cir. reversed PTAB's invalidation of claims related to portable data processing devices.)
Exemplary claim:
Claim 2: Code . . . configured to cause a communication to be transmitted to the . . . node
Claim 4: Wherein the communication caused to be transmitted to the . . . node facilitates transmission of encrypted communications from the . . . node to the terminal.”
Holdings:
Pacific Biosciences of California, Inc. v. Personal Genomics Taiwan, Inc.: “For identifying a single biomolecule”
Claim 1. An apparatus for identifying a single biomolecule, comprising:
a substrate having a light detector; and
a linker site formed over the light detector, the linker site being treated to affix the biomolecule to the linker site;
wherein the linker site is proximate to the light detector and is spaced apart from the light detector by a distance of less than or equal to 100 micrometers.

ZyXEL Communications v. Unm Rainforest Innovations: Motion to Amend [MTA] Pilot Program. (ZyXEL appeals PTAB's grant to UNMRI's motion to amend and finding claim 8 nonobvious; UNMRI cross-appeals on other findings.)
37 C.F.R. § 42.121(b): A motion to amend claims must include a claim listing . . . and set forth: (1) The support in the original disclosure of the patent for each claim that is added or amended; and (2) The support in an earlier-filed disclosure for each claim for which benefit of the filing date of the earlier filed disclosure is sought.

This is a compilation of recent caselaw and high-level subject matter and holdings taken from a recent seminar on the topic:
Am. Axle & Mfg., Inc. v. Neapco Holdings LLC (response due 3/31/21)
Section 101 case involving a process for balancing a vehicle axle. The issues are
7,587,446 Patent Claim 1:
1. A method of transferring media data to a network coupled apparatus, comprising:
(a) maintaining a personal information space identified with a user including media data comprising a directory of digital media files the person al information space being coupled to a server and a network; [. . .]
6,757,696 Patent Claim 1:
1. A controller for a synchronization system, comprising:
a user identifier module;
Synchronoss Techs., Inc. v. Dropbox, Inc., 987 F.3d 1358 (Fed. Cir. 2/12/21)
Claim contains impossibility. Stated the court:
“Here, the asserted claims of the ’446 patent are nonsensical and require an impossibility—that the digital media file contain a directory of digital media files. Adopting Synchronoss’s proposal would require rewriting the claims, but “it is not our function to rewrite claims to preserve their validity.” Allen, 299 F.3d at 1349. We therefore hold that the claims are indefinite as a matter of law under § 112, paragraph 2.”
Means+function. Stated the court:
“If a claim term invokes § 112, paragraph 6, we apply a two-step process for construing the term. The first step is to identify the claimed function. Williamson, 792 F.3d at 1351. The second step is to determine whether sufficient structure is disclosed in the specification that corresponds to the claimed function. Id. If the specification fails to disclose adequate corresponding structure, the claim is indefinite. Id. at 1351–52.
[. . .]
The term “user identifier module” appears in all asserted claims of the ’696 patent. . . . The corresponding text cited by Synchronoss, however, does not detail what a user identifier module consists of or how it operates.
[. . .]
It is not enough that a means-plus-function claim term correspond to every known way of achieving the claimed function; instead, the term must correspond to “adequate” structure in the specification that a person of ordinary skill in the art would be able to recognize and associate with the corresponding function in the claim. See Williamson, 792 F.3d at 1352. Because the term “user identifier module” fails in this regard, we hold that the term is indefinite and, thus, the asserted claims of the ’696 patent are invalid.
1. A method of separation of automobile shredder residue comprising the steps of:
providing automobile shredder residue as a result from a ferrous sorting recovery system;
introducing said automobile shredder residue into an auto mobile shredder residue sorting, non-ferrous recovery system;
non-magnetically sorting magnetic fuzz from said automobile shredder residue with said automobile shredder residue sorting, nonferrous recovery system;
wherein said sorted magnetic fuzz is substantially free of recyclable materials.
IQASR LLC, v. Wendt Corp., 825 Fed App'x 900 (Fed. Cir. Sept. 15, 2020
The Fed. Cir. affirmed district court finding of invalidity based on indefiniteness on claim term “magnetic fuzz” and “low susceptance microparticles.” Stated the court:
scope [to] vary from day-to-day and from person-to-person,' providing 'a moving target that may change over time.' Icon Health & Fitness, Inc. v. Polar Electro Oy, 656 F. App’x 1008, 1016 (Fed. Cir. 2016).
Infinity Computer Prods. v. Oki Data Ams., Inc., 987 F.3d 1053 (Fed. Cir. Feb. 10, 2021)
The court here held that “Indefiniteness may result from inconsistent prosection history statements where the claim language and specification on their own leave uncertainty that, if unresolved, would produce indefiniteness.”
