Short Summary
Lionra Technologies has filed a Director Review request challenging the PTAB’s finding that its dynamic ACL patent claims are obvious. The company alleges procedural violations and improper claim construction based on a late‑filed dictionary definition.
Detailed Summary
In a Request for Director Review, Lionra Technologies Limited contests the PTAB’s Final Written Decision that held claims 15, 17, and 19‑21 of U.S. Patent 7,632,518 unpatentable as obvious over several prior patents. Lionra contends the Board abused its discretion by introducing Exhibit 3001—a dictionary definition of “circuit”—only in the final decision, denying the patent owner a chance to respond, thereby violating the Administrative Procedure Act. The petitioner, Cisco Systems, Inc., relied on that definition in its obviousness analysis under 35 U.S.C. §103(a). Lionra seeks reversal of the unpatentability findings and a reconsideration of claim construction without the improper evidence.
