NIST Keeps IoT Hot with Draft Guidance

Client Alert | 1 min read | 01.22.21

The National Institute of Standards & Technology (NIST) has published three draft addenda to its manufacturer IoT guidance NISTIR 8259, as well as draft guidance for federal agencies, NIST SP 800-213, on integrating IoT devices into their networks. Notably, NIST published the addenda—8259B, 8259C, and 8259D—and 800-213 just days after the enactment of the Internet of Things Cybersecurity Improvement Act of 2020, in which Congress directed NIST to draft and finalize security guidelines for IoT devices procured by the federal government. While neither the 8259 addenda nor 800-213 fall within the Act's purview, they are likely to inform NIST's development of its IoT cybersecurity guidance under the Act. This is particularly true with regard to both 800-213 and addendum 8259D, the latter of which offers a "worked example" of implementing the core 8259 requirements within the specifications of the FISMA process and the NIST SP 800-53 security controls.

Defining Claim Terms by Implication: Lexicography Lessons from Aortic Innovations LLC v. Edwards Lifesciences Corporation

Claim construction is a key stage of most patent litigations, where the court must decide the meaning of any disputed terms in the patent claims.  Generally, claim terms are given their plain and ordinary meaning except under two circumstances: (1) when the patentee acts as its own lexicographer and sets out a definition for the term; and (2) when the patentee disavows the full scope of the term either in the specification or during prosecution.  Thorner v. Sony Comput. Ent. Am. LLC, 669 F.3d 1362, 1365 (Fed. Cir. 2012).  The Federal Circuit’s recent decision in Aortic Innovations LLC v. Edwards Lifesciences Corp. highlights that patentees can act as their own lexicographers through consistent, interchangeable usage of terms across the specification, effectively defining terms by implication....
