“For a claim to a biological material, the enablement requirement of § 112, first paragraph, does not require such assured access to a microorganism deposit as of the filing date; what is required is assurance of access (to the microorganism culture by the public upon issuance of a patent on the application) prior to or during the pendency of the application, so that, upon issuance of a U. S. patent on the application, the public will, in fact, receive something in return for the patent grant. Feldman, 517 F.2d at 1355. Patent Owner has persuaded us that such exception not only applies to a deposit, but also extends to a biological material known and readily available. See 52 Fed. Reg. 34080, 34081. In this case, it is undisputed that TC1507 germplasm was known and readily available to the public by Barbour’s publication date in 2006 (Pet. 49–53), years before the 2014 issuance date of the ’378 patent (Ex. 1001, code 45). Thus, based on the record developed through trial, we agree with Patent Owner that the 2004 application satisfies the enablement requirement as of its application date in 2004. PO Resp. 16–18 (citing 52 Fed. Reg. 34080, 34081). As a result, the challenged claims are entitled to the 2004 priority date and, thus, Barbour does not qualify as prior art.” slip op. at 15

At this stage, Patent Owner’s suggestion that Dr. Hausinger lacks relevant expertise or qualifications of at least a POSA is unpersuasive. The ’283 patent relies on Dr. Hausinger’s own prior work.

“The obviousness-type double patenting rejection does not demonstrate that the earlier filed ’995 patent described the invention, with all its claimed limitations.

(“One shows that one is ‘in possession’ of the invention by describing the invention, with all its claimed limitations, not that which makes it obvious.”). Second, the Examiner’s identification of “common subject matter” consists merely of that which appears in the preamble of challenged claim 8. Although the Examiner stated that there was no apparent reason why the present claims were not presented in the earlier application, Mr. Kitchen presents credible testimony that the clock means limitation “for keeping a predetermined time period after said executing means starts execution of the program or data processing,” did not appear in the earlier filed applications and written description support for it was added in the continuation-in-part ’784 application via new Figure 12.
