Enabled but not described?
Posted by: Bruce in Enablement, Patent Prosecution, Written description, tags: enabling description, Written descriptionIn a seeming paradox, in the magic world of patent filings it is possible to “enable” your invention - that is, explain to someone of skill in your field how to make or use your invention - and yet not fully meet the written description requirement for obtaining a patent (or at least patent coverage for all aspects of your invention). Orlando Lopez, a partner at Burns & Levinson, was kind enough to provide an example where this was an issue:
In a 1971 case again involving chemical subject matter, the court expressly stated that “it is possible for a specification to enable the practice of an invention as broadly as it is claimed, and still not describe that invention.” [**15] In re DiLeone, 58 C.C.P.A. 925, 436 F.2d 1404, 1405, 168 U.S.P.Q. (BNA) 592, 593 (1971). As an example, the court posited the situation “where the specification discusses only compound A and contains no broadening language of any kind. This might very well enable one skilled in the art to make and use compounds B and C; yet the class consisting of A, B and C has not been described.”
Admittedly it is rarely the case, but it certainly shows an internal, logical inconsistancy. It seems to me, in this case, that compounds B and C, being enabled for one skilled in the art, should at least be covered by the doctrine of equivalents, assuming the patent was covering a process for making A.
Similarly, I would expect that a separate patent application for compounds B and C, made by this process, would be tossed out as either anticipated or obvious in light of the patent in this case.
In the same vein, had the enabling description for making compound A in this patent been presented in a journal more than a year before filing, would compounds B and C run into the prior disclosure bar? Seems to me it all needs to hang together.
And it certainly will depend on what the patent specification in question is actually trying to cover. If I come up with a new paint in which oxidized metallic flakes provide some new and beneficial property and enable the process of incorporating the flakes uniformly, but I only describe red paint based on iron (known to look red), should my patent bar someone from using oxidized copper flakes to make green paint? I would think/hope it would!
[This example begs another question - could someone else get a patent on the green paint that I enabled but didn't describe? Admittedly it would be dominated by my patent, but it would bar me from making green paint.]
