Case Brief Summary & Legal Analysis
tl;dr: A patent for a floral arrangement assembly was held invalid. The court found a prior art reference anticipated the invention by rejecting an improperly narrow claim construction and finding a key feature was inherently, though not expressly, disclosed.
Legal Significance: This case reinforces two core patent law doctrines: claim limitations cannot be imported from the specification into the claims, and a prior art reference can anticipate a claim if a limitation is an inherent, necessary result of practicing the reference.

Case Facts & Court Holding
Key Facts & Case Background
Prima Tek, the plaintiff, owned U.S. Patent Nos. 5,410,856 and 5,615,532, which claimed a decorative assembly and method for displaying floral groupings. The key features included a “floral holding material” supporting the flowers “without any pot means,” all wrapped in a decorative sheet. Claim 15 of the ‘856 patent further required a “crimped portion” with an “overlapping fold” in the sheet. Prima Tek sued Polypap, a competitor, for infringing these patents with its Bouquett’O product. Polypap asserted that the patents were invalid as anticipated by a prior art French patent application, the “Charrin reference.” The Charrin reference disclosed an assembly where flowers were placed in moss, which was then wrapped in a waterproof cover tied with a cord. The district court, after a bench trial, found the patents were not anticipated. It reasoned that the Charrin reference did not meet the claim limitations because it construed “floral holding material” to require a material that holds a predetermined shape (which moss does not) and found that Charrin did not explicitly disclose a “crimped portion.” The district court entered judgment for Prima Tek, and Polypap appealed.
Court Holding & Legal Precedent
Issue: Are patent claims for a floral assembly anticipated by a prior art reference when the reference does not expressly disclose every limitation, but the patentee argues for a narrow claim construction based on the specification and the alleged infringer argues one limitation is inherently disclosed?
