No Litigation Found for RE48633; Prior Litigation on Parent Patents Noted
As of May 13, 2026, a comprehensive search of publicly available litigation databases reveals no known litigation involving US Patent No. RE48633.
However, it is important to note that the assignee, Kaavo Inc., was previously involved in significant litigation concerning the patents from which RE48633 is descended. Specifically, Kaavo asserted parent patents U.S. Patent No. 9,043,751 and U.S. Patent No. 8,271,974 in a series of cases in the U.S. District Court for the District of Delaware.
Notable cases involving these parent patents include:
- Kaavo Inc. v. Amazon.com Inc. and Amazon Web Services Inc. (D. Del., Case No. 1:15-cv-00638)
- Kaavo Inc. v. Cognizant Technology Solutions Corp. (D. Del., Case No. 1:14-cv-01192)
- Kaavo Inc. v. Tier 3, Inc., AppFog, Inc., and Savvis Communications Corp. (D. Del., Case No. 1:15-cv-00640)
In these earlier cases, defendants successfully argued that the asserted claims of the parent patents were directed to patent-ineligible subject matter under 35 U.S.C. § 101. For example, in a March 31, 2016 Memorandum Order, the court found certain independent claims of the '974 patent to be drawn to the abstract idea of "setting up and managing a cloud computing environment" without a sufficient inventive concept. Subsequently, in a July 2018 ruling, the court granted Amazon's motion for summary judgment, invalidating the remaining dependent claims on the same grounds.
RE48633 is a reissue of the '974 patent and shares a nearly identical specification with its predecessors. While RE48633 itself has not been litigated, the extensive litigation history and invalidity rulings on its parent patents would be a critical factor in any potential future assertion of this patent.
