Case Brief Summary & Legal Analysis
tl;dr: A biotech company’s patent for DNA probes was challenged for inadequately describing the probes’ structure. The court ruled that referencing a public deposit of the biological material can satisfy the patent law’s written description requirement, reversing the patent’s invalidation.
Legal Significance: Established for the first time that referencing a public deposit of biological material can satisfy the written description requirement of 35 U.S.C. § 112, ¶ 1, providing a crucial “surrogate” description for complex inventions like nucleotide sequences.

Case Facts & Court Holding
Key Facts & Case Background
Enzo Biochem, Inc. held a patent for nucleic acid probes capable of detecting the bacteria causing gonorrhea, Neisseria gonorrhoeae, while distinguishing it from the genetically similar Neisseria meningitidis. The patent claims defined the probes functionally, by their ability to preferentially hybridize to N. gonorrhoeae at a ratio of at least five-to-one over N. meningitidis. The patent specification did not disclose the specific nucleotide sequences of the probes. However, the specification did include the accession numbers for three exemplary probe sequences that Enzo had deposited in the American Type Culture Collection (ATCC), a public depository. The patent included narrow claims directed to the deposited sequences and their variants, as well as broader genus claims covering any sequence meeting the functional hybridization ratio. When Enzo sued for infringement, the defendants moved for summary judgment, arguing the claims were invalid for failing the written description requirement of 35 U.S.C. § 112, ¶ 1. The district court agreed, holding that describing a nucleic acid by its function was insufficient under Regents of the University of California v. Eli Lilly & Co., and that a biological deposit could only satisfy the enablement requirement, not the written description requirement.
Court Holding & Legal Precedent
Issue: Can a reference in a patent specification to a deposit of biological material in a public depository satisfy the written description requirement of 35 U.S.C. § 112, ¶ 1, for claims to that material?
Yes. The court reversed the summary judgment of invalidity, holding that referencing Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
