In Re PersonalWeb Technologies LLC
Personal Web’s patents share a largely common specification and claim priority to an abandoned patent application, which was filed in 1995. According to the specification, there was a problem with the way computer networks identified data in their systems. There was “no direct relationship between the data names” and the contents of the data item. Computer networks could become clogged with duplicate data, and the efficiency and integrity of data processing systems could be impaired. The inventors purported to solve this problem by devising “True Names” for data items. The system created a “substantially unique” identifier for each data item that depended only on the content of the data itself and did not depend on purportedly less reliable means of identifying data items, such as user-provided file names. PersonalWeb sued Amazon for patent infringement. After the district court issued its claim construction order, PersonalWeb stipulated to the dismissal of all its claims against Amazon with prejudice; the court subsequently entered judgment against PersonalWeb.In 2018, PersonalWeb filed dozens of new lawsuits against website operators, many of which were Amazon’s customers. Amazon intervened. The Federal Circuit affirmed a declaratory judgment that PersonalWeb’s lawsuits against Amazon’s customers were barred as a result of the prior lawsuit brought by PersonalWeb against Amazon.

VirnetX Inc. v. Apple Inc.
VirnetX appealed the Patent Trial and Appeal Board's decision related to three inter partes reexaminations maintained by Apple and Cisco. In this case, the PTO concluded that Apple was not barred from maintaining its reexams by the estoppel provision of the pre-America Invents Act (AIA) version of 35 U.S.C. 317(b), and the Board affirmed the examiner's determination that the claims of U.S. Patent Nos. 7,418,504 and 7,921,211 are unpatentable as anticipated or obvious over the prior art of record. The '504 and '211 patents describe systems and methods for establishing a secure communication link between a first computer and a second computer over a computer network, such as the Internet.The Federal Circuit held that there has been a final decision entered against Apple that it has not sustained its burden of proving invalidity, and thus section 317(b) estoppel applied to the Apple reexams. Therefore, the court vacated the Board's decisions in the Apple reexams with respect to claims 1–35 of the '504 patent and claims 36–59 of the '211 patent and remanded with instructions to terminate. The court affirmed the Board's decision on all remaining claims of both patents in the Apple reexam not subject to section 317(b) estoppel and fully affirmed the Board's decision regarding the claims of the '211 patent in the Cisco reexam.
