The provided text Why the Patent in Ravenwhite v Wal-Mart Appears Invalid and the Case Merits Dismissal, from ByteLaw® discusses the potential invalidity of U.S. Patent No. 10,594,823, central to a lawsuit see RAVENWHITE LICENSING LLC vs Wal-Martbetween Ravenwhite Licensing LLC and Wal-Mart Inc. The article argues that the patent, which claims a method for identifying users using two different cookie types in separate browser storage, lacks novelty and non-obviousness. It highlights extensive prior art and a Patent Trial and Appeal Board (PTAB) decision to institute an inter partes review, indicating a "reasonable likelihood" of unpatentability. Furthermore, the analysis suggests the patent's claims are fatally abstract under the Alice framework, lacking an inventive concept beyond an abstract idea implemented with generic computing components. Ultimately, ByteLaw® contends that Wal-Mart has a strong basis for dismissal with prejudice, aiming to prevent further litigation based on what it considers an invalid patent.
