Teva v astrazeneca invalidating a patent with secret prior art

These are distinct concepts, each of which has to be satisfied and each of which has its own rules.

Prior disclosure is the first requirement to be satisfied for matter to anticipate an invention.

The United States has a "first to invent" patent system.

This principle is embodied, among other places, in section 102(g)(2) of the Patent Code, which states that a person is not entitled to a patent if "before such person's invention thereof, the invention was made in this country by another inventor who had not abandoned, suppressed, or concealed it." 35 U.

The Patents Court considered the requirement for the prior art “inevitably” to result in a novelty-destroying disclosure in Kirin-Amgen Inc. It was held that “the law of patents is ultimately concerned with practicality”, and so a prior art experiment which, when performed, reliably produced a particular result “more than 99 percent of the occasions on which it is conducted” would be regarded for the purposes of disclosure as “inevitably” leading to the result in question.

In Dr Reddy’s Laboratories (UK) Ltd v Eli Lilly and Co Ltd [2008] EWHC 2345 (Pat), [2009] FSR 5, the Patents Court held that where the skilled person would have recognised that there were errors in a prior disclosure, the question to be considered was whether there was a clear and unambiguous disclosure of the invention, not whether the skilled person would have concluded that the document probably disclosed the invention. It follows that a claim which defines an invention by reference to parameters, for example of a process or a product, is anticipated by a disclosure which when put into practice would necessarily fall within the scope of the claim, even if the disclosure does not refer to these particular parameters. In T 303/86 (CPC Int) [1993] EPOR 241 the Technical Board of Appeal of the EPO considered anticipation arising from two cook-book recipes of a process for making flavour concentrates from vegetable or animal substances by extraction with fat solvents under pressure in the presence of water.

To constitute a prior disclosure of an invention, the matter relied upon as prior art must disclose subject matter which, if performed, would necessarily result in infringement of the patent.

This infringement test is detailed by the Court of Appeal in General Tire & Rubber Company v Firestone Tyre & Rubber Company Limited, [1972] RPC 457, at pages 485-6:- If the prior inventor’s publication contains a clear description of, or clear instructions to do or make, something that would infringe the patentee’s claim if carried out after the grant of the patentee’s patent, the patentee’s claim will have been shown to lack the necessary novelty, that is to say, it will have been anticipated.

[Alleged infringer] contends that claim(s) [ ] of the [ ] patent is/are invalid because the claimed invention(s) is/are anticipated or because [patent holder] lost the right to obtain a patent.[A description is a “printed publication” only if it was publicly accessible.] (3) [Patent holder] has lost her or his rights if the claimed invention was already patented or described in a printed publication, anywhere in the world by [patent holder] or anyone else, more than a year before [insert date], which is the effective filing date of the application for the [ ] patent.An invention was patented by another if the other patent describes the same invention claimed by [patent holder] to a person having ordinary skill in the technology. For the purposes of summary judgment only, Astra Zeneca also conceded infringement of the asserted '502 patent claims, meaning that identity of invention was established.

Teva filed the lawsuit in the EDPA, near the headquarters of its U. Astra Zeneca argued that it had made batches of tablets containing the same ingredients, in the same amounts, as the CRESTOR tablets accused of infringement by Teva before the earliest invention date claimed by Teva for its '502 patent formulation—December 1, 1999. The Court added that "The discovery of this inherent property does not make the pharmaceutical compositions claimed by Teva—which Astra Zeneca undisputedly made first—new." D.

RE39,502 ("the '502 patent"), due to Astra Zeneca's prior invention. According to Teva, Astra Zeneca's failure to appreciate this was "fatal to its claim of prior invention." D. It also noted that "conception and reduction to practice require 'contemporaneous recognition and appreciation [T]he inventor need not 'establish that he recognized the invention in the same terms as those recited in the [claims]' as '[t]he invention is not the language of the claims but the subject matter thereby defined.'.

An invention defined in a claim lacks novelty if the specified combination of features has already been anticipated in a previous disclosure.In Smith Kline Beecham Plc’s ( Paroxetine Methanesulfonate) Patent [2006] RPC 10, the House of Lords held there were two requirements for anticipation: prior disclosure (see 2.03 to 2.09) and enablement see 2.10.
