Judge Sleet grants summary judgment motion of no infringement

Judge Gregory M. Sleet, recently granted defendants’ motion for summary judgment of non-infringement based on upon the Court’s construction of the limitation “changing [price] information.”  Quest Licensing Corporation v. Bloomberg L.P., No. 14-561-GMS (D. Del. Jan. 19, 2017).  Defendants argued that summary judgment was appropriate because “defendants’ accused systems do not receive or supply ‘only data that has changed’ as required by all of the asserted claims of the patent-in-suit.”  Id. at 3.  Judge Sleet agreed.  The Court previously construed the term “changing information” to mean “only [price] data that has changed,” and it was undisputed that the accused systems receive and supply information that “always includes non-changing information such as the stock symbol.”  Id. at 5-6.  Judge Sleet was not persuaded that the Court should revisit its claim construction ruling.  Id. at 6.
