![Section 35 U.S.C. § 271(a) provides that “whoever without authority makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent thereof, infringes the patent.” 35 U.S.C. § 271(a). “[D]irect infringement is a strict-liability offense that does not require knowledge of the patent or intent to infringe.” Lifetime Indus., Inc. v. Trim-Lok, Inc., 869 F.3d 1372, 1377 (Fed. Cir. 2017); see also Global-Tech Appliances, Inc. v. SEB S.A., 563 U.S. 754, 761 n.2 (2011) (“Direct infringement . . . require[s] no more than the unauthorized use of a patented invention.”). To determine whether a design patent has been infringed, courts apply an “ordinary observer” test, “which provides that ‘if, in the eye of an ordinary observer, giving such attention as a purchaser usually gives, two designs are substantially the same, if the resemblance is such as to deceive such an observer, inducing him to purchase one supposing it to be the other, the first one patented is infringed by the other.’” Ontel Prods.
