PersonalWeb Technologies Sues Match Group for Patent Infringement

PersonalWeb Technologies has filed  a case against Match Group for patent infringement. The move comes as Match Group is challenging Bumble and Tantan on similar grounds.

The case, overseen by the US District Court of Delaware, concerns five patents co-owned by PersonalWeb and Level 3 Communications.

The patents concern “fundamental aspects of cloud computing, including the identification of files or data and the efficient retrieval thereof in a manner which reduces bandwidth transmission and storage requirements.”

Specifically, they concerns cryptographic hash functions which give files a unique identifier, preventing the duplication of data in storage systems.

Before the technology, the plaintiff claims “No solution existed to ensure that identical file names referred to the same data, and conversely, that different file names referred to different data.”

Their solution has been dubbed “True Names”, and was patented in 1999.

PersonalWeb’s Prayer for Relief reads:

“WHEREFORE, Plaintiff PersonalWeb requests entry of judgment in its favor and against Defendant as follows:

  1. a) Declaration that Defendant has infringed U.S. Patent Nos. 5,978,791, 6,928,442, 7,802,310, 7,945,544 and 8,099,420 as described in this action;
  1. b) Awarding the damages arising out of Defendant’s infringement of U.S. Patent Nos. 5,978,791, 6,928,442, 7,802,310, 7,945,544 and 8,099,420, together with pre-judgment and post-judgment interest, in an amount according to proof;
  1. c) An award of attorneys’ fees pursuant to 35 U.S.C. § 285 or as otherwise permitted by law; and
  1. d) For costs incurred and such other and further relief as the Court may deem just and proper.”
