What Happened in Kahler v. Kansas?

SHERRY F. COLB

Cornell law professor Sherry F. Colb describes how the U.S. Supreme Court purported to allow the state of Kansas to substitute one insanity defense for another, but in fact approved its abolishment of the insanity defense altogether. Colb explains the difference between the insanity defense—an affirmative defense to the commission of a crime—and facts that negate mens rea—the mental element of a crime. Colb also notes how in dissent, Justice Stephen Breyer made a case for veganism, albeit probably inadvertently.

Dana-Farber Cancer Institute v. Ono Pharmaceutical Co., Ltd.

Docket: 19-2050

Opinion Date: July 14, 2020

Judge: Alan David Lourie

Areas of Law: Drugs & Biotech, Intellectual Property, Patents

Each patent at issue claims a method of treating cancer by administering antibodies targeting specific receptor-ligand interactions on T cells, which are responsible for processing information to develop an immune response in the body using receptors on their surfaces. The named inventor Dr. Honjo, a professor at Kyoto University, had shared information with Drs. Wood and Freeman until about 2001. In 2002, Honjo filed his patent application in Japan. Each patent at issue case claims priority from that patent application; none include Freeman and Wood as inventors. The Federal Circuit affirmed that Drs. Freeman and Wood should be deemed inventors of the subject matter of the patents alongside Dr. Honjo, 35 U.S.C. 116(a). The inventorship of a complex invention may depend on partial contributions to conception over time, and there is no principled reason to discount genuine contributions made by collaborators because portions of that work were published prior to conception for the benefit of the public. Earlier publication of an invention is obviously a potential hazard to patentability, but the publication of a portion of a complex invention does not necessarily defeat joint inventorship of that invention.

Packet Intelligence LLC v. NetScout Systems, Inc.

Docket: 19-2041

Opinion Date: July 14, 2020

Judge: Alan David Lourie

Areas of Law: Intellectual Property, Patents

Packet’s patents teach a method for monitoring packets exchanged over a computer network. A stream of packets between two computers is called a connection flow. Monitoring connection flows cannot account for disjointed sequences of the same flow in a network. The specifications explain that it is more useful to identify and classify “conversational flows,” defined as “the sequence of packets that are exchanged in any direction as a result of an activity.” Conversational flows provide application-specific views of network traffic and can be used to generate helpful analytics to understand network load and usage. The 789 patent recites apparatus claims’ the 725 and 751 patents recite method claims. Packet asserted claims against NetScout’s products under 35 U.S.C. 102. The jury found all claims willfully infringed, rejected NetScout’s invalidity defenses, and awarded pre-suit ($3.5 million) and post-suit ($2.25 million) damages. The court issued findings, rejecting NetScout’s section 101 invalidity defense, enhanced damages by $2.8 million, and awarded an ongoing royalty for post-verdict infringement. The Federal Circuit reversed in part and vacated the award of enhanced damages. The district court erred in denying NetScout’s motion for judgment as a matter of law on pre-suit damages. Packet is barred from recovering damages for pre-suit sales of the NetScout products because it failed to comply with the marking requirement. The court otherwise affirmed.
