Plano Texas entity Pinek, a patent holding company, sued Westford 2019s Visonic of infringing U.S. Patent No. 7,233,256, which is directed to systems and methods for receiving a signal to trigger a pyroelectric activation system. Pinek asserts that Visonic 2019s Long Range Pet Immune PIR Motion Detector infringes at least claim 1 of the 2018256 patent, and seeks monetary, but not injunctive, relief. Pinek filed eight additional cases alleging infringement of the 2018256 patent in the last three months, one of which appears to have settled. Judge Talwani has been assigned to the matter.
