Paramus, NJ.  July 16, 2013. The US District Court for the Northern District of California issued an Order and Judgment that Shingle Springs, CA-based company Your Last Gutter Guard committed multiple acts of infringement on several MGP Manufacturing LLC patents for a microfiltration or micromesh gutter guard.  MGP produces MasterShield® Gutter Protection.

Defendant Your Last Gutter Guard (“YLGG”) manufactured and offered for sale a micromesh gutter guard utilizing MGP’s micromesh technology.

Under the terms of the Order, YLGG acknowledged that inventor Edward A. Higginbotham and MGP have expended a great deal of time, effort and resources developing its product MasterShield® and its related patents, including U.S. Patent No. 8,397,436, RE42,896 and RE43,555 (collectively, the “MGP Patents”).
