Judge Farnan recently denied plaintiff’s motion for a preliminary injunction related to handheld mobile computers. Symbol Technologies, Inc. v. Janam Technologies LLC, C.A. No. 08-340-JJF (D. Del. July 20, 2010). Judge Farnan found that plaintiff had shown a likelihood of success on the merits that two of plaintiff’s patents-at-issue were infringed. Id. at 16-17, 29. However, Judge Farnan also found that defendant “raised a substantial question” whether claims of the patents were invalid and plaintiff failed to prove that the defense lacked “substantial merit or [was] reasonably likely to fail.” Id. at 22; see also id. at 28, 33.
