INTRODUCTION 2 The CVC inventors revolutionized the field of genome editing, giving the world a new 3 system capable of cleaving and editing genes in eukaryotic cells. By identifying for the first time 4 the necessary and sufficient components of the Type II CRISPR-Cas9 cleavage complex and 5 further modifying the RNAs into a single-guide (sgRNA) format, the CVC inventors provided a 6 simple, programmable tool for site-specific gene editing in eukaryotic cells. By the time Zhang 7 learned of CVC’s single-guide CRISPR-Cas9 system, the CVC inventors had already conceived 8 multiple specific embodiments of the invention and were diligently working to reduce the 9 invention to practice. 10 Count 1 recites a composition: a system or a eukaryotic cell comprising a sgRNA 11 CRISPR-Cas9 system. Conception of that composition is complete “when the idea is so clearly 12 defined in the inventor's mind that only ordinary skill would be necessary to reduce the invention 13 to practice, without extensive research or experimentation.” Burroughs Wellcome Co. v. Barr 14 Labs., Inc., 40 F.3d 1223 (Fed. Cir. 1994) (citing Sewall v. Walters, 21 F.3d 411 (Fed. Cir. 1994) 15 and Coleman v. Dines, 754 F.2d 353 (Fed. Cir. 1985)). In accordance with that standard, the 16 CVC inventors unquestionably conceived of the invention before Broad’s alleged June 26 17 conception. By then, CVC had already documented at least two specific embodiments that they 18 later reduced to practice: (1) vectors to express the sgRNA and Cas9 protein to cleave the 19 CTLA6 gene in human cells, and (2) a pre-formed sgRNA/Cas9 ribonucleoprotein (RNP) 20 complex that CVC had already demonstrated works in vitro and subsequently simply 21 microinjected into fish cells to cleave DNA. During the critical period, CVC worked diligently 22 to reduce to practice both embodiments of the invention, achieving multiple actual reductions to 23 practice in a matter of months and requiring no further inventive steps.
