MTD had a patent for steering and driving systems for zero turn radius vehicles, such as lawn mowers. The patent was challenged in IPR, where the Board had to construe the claim term “mechanical control assembly … configured to” perform a function. The Board construed the term as not being governed by 35 U.S.C. §112, ¶6, and held the claims to be obvious.
