Orthokinetics, Inc. v. Safety Travel Chairs, Inc.
Court of Appeals for the Federal Circuit
806 F.2d 1565 (1986)
Relevant factsFree
STC began selling a wheelchair similar to Orthokinetics' patented children's travel wheelchair years after the patent issued, and argued the patent was invalid for failing to particularly point out and distinctly claim the invention; the jury, after hearing expert testimony that a skilled artisan could understand the claimed invention from the specification, found the patent valid and infringed, but the district court granted STC's motion for judgment notwithstanding the verdict.
IssueFree
Whether, in order for an inventor to secure a patent, he must both particularly point out and distinctly claim his invention.
