Novelty: What’s New?

Patent Law

Prof Merges

9.14.2010

Clearing Up Two Issues

• Indefiniteness: see group email (it is a question of law, but nevertheless based on complex facts)

• Best mode: disclose actual best mode as part of a short “laundry list” is OK; “burying” in a long list, maybe not (Randomex)

Three Main Issues Under Novelty

• What is the prior art: what is a “reference”?

• Timing Issues: What is in, and out, of the “prior art”?

• Identity standard: how similar does a prior art reference have to be to anticipate (destroy novelty, invalidate) a patent?

Subsidiary Issue

• Practical: burden of proof, details of proving prior art dates

35 USC 102

“A person shall be entitled to a patent unless . . . .”

Novelty § 102

A person is not entitled to a patentif the invention was:

• in the prior art (as defined by § 102 (a), (e), (g))

• barred under § 102 (b), (c), (d)

Key Distinction

• Though both covered by § 102, novelty and statutory bars are very different

• Novelty: is it new?

• Statutory bars: did you file before the cutoff date? Did you file on time?

Novelty (Anticipation) [§ 102(a)] Versus Statutory Bars [§ 102(b)]

• Novelty/Anticipation concerned with NEWNESS – is it original to the patent applicant/patentee?

• Statutory Bars concerned with TIMELINESS – did the inventor file soon enough?

§ 102. Novelty and loss of right to patent

A person shall be entitled to a patent unless

(a) the invention was known or used by others … before the invention thereof by the applicant for patent, or

(b) the invention was patented or described in a printed publication

…, more than one year prior to the date of the application for patent in the United States, or . . . .

What is the key difference?

• The CRITICAL DATE is different for novelty vs. the statutory bars

• Novelty: date of invention

• Statutory bars: Filing date minus one year

In re Robertson

• Page 365

• Held: Claim 76 not anticipated

• United States Patent 5,279,604 Robertson , et al. January 18, 1994

Mechanical fastening systems with disposal means for disposable absorbent articles

• Abstract• A disposable absorbent article with a mechanical fastening system having

an additional fastening element so as to provide convenient disposal of the absorbent article. The mechanical fastening system preferably comprises a tape tab having a first fastening element, a landing member comprising a second fastening element engageable with the first fastening element, and

an additional fastening element for allowing the absorbent article to be secured in a configuration that provides convenient disposal of the absorbent article. The additional fastening element preferably comprises a second fastening element affixed to the backing surface of at least one of the tape tabs

Wilson specification

“Disposal of the soiled garment . . . Is easily accomplished by folding the front panel . . . Inwardly and then fastening the rear pair of mating fastening members to one another, thus neatly bundling the garment . . .”

P. 364Anticipation … requires that “each

and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” Verdegaal Bros., Inc. v. Union Oil Co., 814 F.2d 628, 631, 2 U.S.P.Q.2D (BNA) 1051, 1053 (Fed. Cir. 1987)

Inherency – p. 364

“To establish inherency, the extrinsic evidence “must make clear that the missing descriptive matter is necessarily present in the thing described in the reference, and that it would be so recognized by persons of ordinary skill.”

• Wilson reference– Closure member– Landing member

– Disposal means with . . .

• 3rd fastening element?

• Wilson specification: “fasten rear pair of mating fastening members to one another . . .” p 368

Fed Cir“The Board made no attempt to show that the

fastening mechanisms of Wilson that were used to attach the diaper to the wearer also “necessarily” disclosed the third separate fastening mechanism of claim 76 used to close the diaper for disposal, or that an artisan of ordinary skill would so recognize. It cited no extrinsic evidence so indicating.”

“[T]he Board failed to recognize that the third mechanical fastening means in claim 76, used to secure the diaper for disposal, was separate from and independent of the two other mechanical means used to attach the diaper to the person. .. [T]he Board’s analysis rests upon the very kind of probability or possibility — the odd use of fasteners with other than their mates — that this court has pointed out is insufficient to establish inherency.”

Bd of Appeals opinion

“[A]n artisan would readily understand the disposable absorbent garment of Wilson . . . as being inherently capable of [making the third fastening element] mechanically engageable with [the first fastening element]” — i.e., using the secondary closure not with its mate, but with one of the primary snap fasteners.”

In re Klopfenstein

• 380 F.3d 1345 (Fed Cir 2004)

• “Printed Publications” for the modern era . .

• Page 405

In October 1998, the appellants, along with colleague M. Liu, presented a printed slide presentation entitled "Enhancement of Cholesterol-Lowering Activity of Dietary Fibers By Extrusion Processing" at a meeting of the American Association of Cereal Chemists ("AACC"). The fourteen-slide presentation was printed and pasted onto poster boards. The printed slide presentation was displayed continuously for two and a half days at the AACC meeting.

If this food is so safe, why do we have to wear hardhats?

Can you believe people actually eat this stuff?

The statutory phrase "printed publication" has been interpreted to mean that before the critical date the reference must have been sufficiently accessible to the public interested in the art; dissemination and public accessibility are the keys to the legal determination whether a prior art reference was "published.“ -- p. 406

• Billboard hypothetical: p. 406

• “’public accessibility’ has been called the touchstone in determining whether a reference constitutes a ‘printed publication,’” In re Hall

– NOT just indexing

• “The reference was shown with no stated expectation that the information would not be copied or reproduced by those viewing it.”

The factors relevant to the facts of this case are: the length of time the display was exhibited, the expertise of the target audience, the existence (or lack thereof) of reasonable expectations that the material displayed would not be copied, and the simplicity or ease with which the material displayed could have been copied.

Where professional and behavioral norms entitle a party to a reasonable expectation that the information displayed will not be copied, we are more reluctant to find something a "printed publication." This reluctance helps preserve the incentive for inventors to participate in academic presentations or discussions. Where parties have taken steps to prevent the public from copying temporarily posted information, the opportunity for others to appropriate that information … is reduced. -- p. 409

– TOO BAD!

Hafner

• The 1961 publication enables for purpose of anticipation even though it does not enable for purposes of 112.

• Key difference is that enablement for anticipation does NOT require a known use; section 112 does.

• Anticipation prevents any “backsliding” for the public domain. Prior art cannot be patented in a product claim even if the prior art does not yet have a use!
