Advanced Ground Info. Sys., Inc. v. Life360, Inc.

Advanced Ground Information Systems, Inc. (“AGIS”) appeals the decision of the United States District Court for the Southern District of Florida in Advanced Ground Information Systems, Inc. v. Life360, Inc., No. 14-cv-80651 (S.D. Fla. Nov. 21, 2014) (J.A. 2–37), which found that claims 3 and 10 of U.S. Patent No. 7,031,728 (“the ’728 patent”) and claims 5 and 9 of U.S. Patent No. 7,672,681 (“the ’681 patent”) (together, the “patents-in-suit”) invoke 35 U.S.C. § 112, ¶ 6, and that the claims are indefinite under 35 U.S.C. § 112, ¶ 2 (2006).1 Although the district court found these claims indefinite, it did not address the issue of invalidity because Appellee, Life360, Inc., (“Life360”) did not request a finding of invalidity. The parties subsequently stipulated that these claims were invalid for indefiniteness, see J.A. 857, and the court entered its Final Judgment on May 12, 2015, see J.A. 1. For the reasons articulated below, we affirm the district court’s decision that the claims are indefinite, and accordingly conclude that the asserted claims are invalid.
