SpaceTime3D, Inc. v. Apple Inc.

SpaceTime3D, Inc. v. Apple Inc. The Federal Circuit affirmed the Board’s obviousness determinations. The court rejected SpaceTime3D’s claim-construction arguments for the disputed ordering and replacement limitations and held that substantial evidence supported the Board’s findings that the Anthony-Hanggie combination taught those limitations. The decision reinforces that patentees cannot narrow GUI claims by importing state-preservation or mutually exclusive functionality requirements not found in the claim language or intrinsic record. Affirmed. The disputed claims cover displaying application images in a simulated 3D space ordered by user activity and replacing the 3D images with a corresponding application object in 2D space upon selection. For the ordering limitation, the court held that the claim requires determining the last time one of three enumerated opening-and-interacting events occurred, not separately determining the timing of six individual actions. For the replacement limitation, the court refused to import a construction from a related IPR involving different claim language requiring a previously rendered webpage; the claims here did not require returning to an object in its precise prior state. The court also held that the claims distinguish images from objects without requiring mutually exclusive functionality, and substantial evidence supported the Board’s finding that Hanggie’s 3D textured window representations and underlying 2D application windows satisfied that distinction. Applying the parties’ agreed constructions of 3D and 2D space, substantial evidence supported the Board’s finding that selecting and maximizing a 3D-displayed window in the Anthony-Hanggie combination replaced the 3D timeline with the corresponding 2D application window. § 103 claim construction non-precedential waiver / forfeiture § 103 claim construction non-precedential waiver / forfeiture § 103 claim construction non-precedential
