U.S. Patent No. 5,235,326, multi-mode radio frequency ID system for reading encoded biocompatible chips
Found valid and willfully infringedB f bl f bl d But unenforceable for inequitable conduct
Avid Identification Systems, Inc. v. Crystal Import Corp. (Fed. Cir. 2010)Crystal Import Corp. (Fed. Cir. 2010)
Dr. Hannis Stoddard Dr. Hannis Stoddard a veterinarian decided to form the Avid Corporation after visiting an animal
shelter to reclaim his own lost dog
St dd d hi d th i t d l hi d Stoddard hired three engineers to develop a chip and reader system, where the reader could read both the unencrypted chips on the market as well as encrypted yp p ypchips produced by Avid
Avid Identification Systems, Inc. v. Crystal Import Corp. (Fed. Cir. 2010)Crystal Import Corp. (Fed. Cir. 2010)
Dr. Stoddard had a demonstration at a trade show in A il 1990April 1990
Patent application was filed in August 1991 on the multi-mode system naming the three engineers as inventors mode system, naming the three engineers as inventors
Court found Dr. Stoddard’s trade show demonstration was material prior art under section 102(b) and that it p ( )was withheld from the PTO with deceptive intent
On appeal, Avid argues that 1) the demonstration was not material and that 2) Dr. Stoddard did not have a duty of candor under Rule 56
Avid Identification Systems, Inc. v. Crystal Import Corp (Fed Cir 2010)Crystal Import Corp. (Fed. Cir. 2010) Materiality under Rule 56 The demonstration was related to a precursor product that The demonstration was related to a precursor product that
did not contain all of the elements of the ‘326 patent claims A jury was presented with the trade show information and still found
the patent validthe patent valid
Held: “material” should not be confused with “invalidating” A reasonable examiner may find a particular piece of information
important to a determination of patentability, even if that information does not actually invalidate the patent
District court found that the precursor product, while not invalidating, reflected the closest prior art, and thus was highly material

Consequences of Breach of Rule 56 DutyConsequences of Breach of Rule 56 Duty
37 C.F.R. 1.56 : “[N]o patent will be granted on an application in connection with which … the duty of disclosure was violated through bad faith or intentional misconduct.”
Subsequent litigation may result in a finding of inequitable Subsequent litigation may result in a finding of inequitable conduct, rendering entire patent – and possibly related patents as well – unenforceable
Inequitable conduct may include affirmative misrepresentation of a material fact, failure to disclose material information, or submission , ,of false material information, coupled with an intent to deceive.
Determining Inequitable ConductDetermining Inequitable Conduct
Party asserting inequitable conduct must prove threshold level of materiality and intent
Court then determines inequitable conduct by balancing the levels of materiality and intentof materiality and intent In other words, a greater showing of one factor may make up for a
lesser showing of the other
Because penalty for inequitable conduct is so severe, courts attempt to maintain a high standard so as not to punish “the patentee… [who] committed minor missteps or acted with minimal culpability or in good faith.” Therasense, Inc. v. Becton (Fed. Cir. 2010).
Inequitable Conduct Inequitable Conduct -- MaterialityMateriality
Different standards applied to determine materiality Objective “but for” – the misrepresentation is material if, but for the
i i h ld h b i dmisrepresentation, the patent would not have been issued.
Subjective “but for” – the misrepresentation is material if it caused the examiner to approve the application for patent when he would not otherwise have done so
“But it may have been” – information material if it might reasonably have affected y g ythe examiner's decision as to patentability
“Reasonable examiner” standard – based on pre-1992 version of Rule 56; requires a substantial likelihood that a reasonable examiner would consider the information important in deciding whether to allow the application to issue as a patentimportant in deciding whether to allow the application to issue as a patent.
Present-day Rule 56
“Merely cumulative” references are not material and need not be discloseddisclosed
Inequitable Conduct Inequitable Conduct -- IntentIntent
Independent from materiality Materiality does not presume intenty p
Must be shown that applicant had the ifi i t t t i l d d i th specific intent to mislead or deceive the
USPTO In a case involving nondisclosure of
information, evidence must show that the applicant made a deliberate decision to withhold a known material
freference

Dayco Products, Inc. v. Total Containment, Inc (Fed. Cir. 2003) CAFC indicates for first time that an office action from one patent p
application might be material to an examiner of a separate, related application.
Two families of patent applications were pendingp pp p g ‘196 family of applications was before Examiner Nicholson
Issued rejections 3 times based on Wilson reference
Application family resulting in patents-in-suit was before Examiner Arolapp y g p The two application families had substantially identical claims
Nicholson was made aware of patents-in-suit Arola though was not informed of the existence of ‘196 applications of Arola, though, was not informed of the existence of 196 applications, of
Nicholson’s rejections, or of the Wilson reference
Materiality Materiality –– Recent DecisionsRecent Decisions
Dayco Products, Inc. v. Total Containment, Inc (Fed. Cir. 2003) (continued)( ) District Court (W.D. Mo.) granted summary judgment of
unenforceability based on the three items not disclosed to Arola CAFC (Mayer Michel and Dyk) – SJ was improper CAFC (Mayer, Michel, and Dyk) SJ was improper
Co-pendency of applications was material because Arola could have issued double-patenting rejection if he had been made aware, but intent not found because the patents-in-suit were disclosed to Nicholsonp
Nicholson’s reliance on the Wilson reference not dispositive of materiality –more factual analysis required; intent not found because attorney affidavit explaining conclusion that Wilson not material was supplied
CAFC did note that contrary decision of another examiner reviewing a substantially similar claim may be material under both the “reasonable examiner” and Rule 56 standards.

McKesson Info. Solutions v. Bridge Medical (Fed. Cir. 2007) Three applications pending, related to similar subject matter
‘527 Application, which matured into patent-in-suit, was before Examiner Trafton
‘149 Application was before Examiner Lev Had Baker reference before him
I d j i Issued rejections
‘195 Application, which shared parent application with ‘527 Application, was also before Examiner Trafton
Baker reference were not disclosed to Examiner Trafton in ‘527 Applicationa e e e e ce we e ot sc ose to a e a to 5 7 pp cat o Examiner Lev’s rejections in ‘149 Application were not disclosed to Examiner
Trafton in ‘527 Application Examiner Trafton’s allowance of ‘195 Application were not cited back to Trafton pp
in ‘527 Application

McKesson Info. Solutions v. Bridge Medical (Fed. Cir. 2007) (continued)(continued) District Court (E.D. Ca.) found patent-in-suit unenforceable CAFC (Newman, Bryson, Clevenger) affirmed
B k f l d h l Baker reference was noncumulative art and thus material Regarding Examiner Lev’s rejections: showing substantial similarity between
the rejected claims and the claims at issue was sufficient to show materiality, but not necessary – rejected claims in co pending application need not be but not necessary – rejected claims in co-pending application need not be substantially similar in order to be material.
Examiner Trafton’s allowance was material because materiality not limited to info that would invalidate the claims under investigationg
Allowance of ‘195 application could have given rise to double-patenting rejection, so allowance was material
Applicant could not assume that Examiner Trafton would remember his decision to grant one application while examining claims of different decision to grant one application while examining claims of different application

Larson Mfg. Co. v. Aluminart Prods. Ltd. (Fed. Cir. 2009) Larson asserted ‘998 Patent against Aluminart Larson asserted 998 Patent against Aluminart Aluminart requested reexamination, which was granted, and litigation
was stayed ‘039 Continuation of ‘988 Patent was prosecuted while reexamination of 039 Continuation of 988 Patent was prosecuted while reexamination of
‘988 Patent was pending Two office actions in ‘039 Continuation were cited to the reexam panel Third and fourth office actions were not cited Third and fourth office actions were not cited
Reexamination concluded with issuance of reexam certificate, and stay of litigation was lifted
Al i t th t d i it bl d t i t L f f il t Aluminart then asserted inequitable conduct against Larson for failure to disclose third and fourth office actions and three prior art references to reexam panel
Materiality Materiality –– Recent DecisionsRecent Decisions
Larson Mfg. Co. v. Aluminart Prods. Ltd. (Fed. Cir. 2009) (continued)(continued) District Court (S.D.) held ‘998 Patent unenforceable CAFC (Schall, Clevenger, Linn) remanded
U i d i f l l i Uncited prior art references were merely cumulative Uncited office actions were material because they contained adverse
decisions by another examiner that refuted or was inconsistent with the patentability of substantially similar claims patentability of substantially similar claims.
In particular, the fourth office action contained a new rejection with an interpretation of a reference that was different from the reexamination panel’s interpretation of the same reference
Case was remanded for s determination of whether withholding of office actions alone constituted inequitable conduct
Court noted that materiality does not presume intent and nondisclosure by itself cannot satisfy deceptive intent requirementitself cannot satisfy deceptive intent requirement.

Therasense, Inc. v. Becton (Fed. Cir. 2010) Abbott (successor to Therasense) was owner of ’551 Patent for an ( )
electrochemical sensor for testing whole blood without any membrane over the electrode
‘382 Patent, initially filed by one of Abbott’s predecessors, was cited as y y pprior art during prosecution of the application that matured into the ‘551 Patent ‘382 Patent broadly claimed a membraneless sensor, and its specification
disclosed membraneless sensors The ‘382 Patent specification expressly noted: “Optionally, but preferably
when being used on live blood, a protective membrane surrounds both the en me and the mediat r la ers ermeable t ater and l c se m lec les”enzyme and the mediator layers, permeable to water and glucose molecules.”

Therasense, Inc. v. Becton (Fed. Cir. 2010) (continued) In prosecuting the application that matured into ‘551 patent, Abbott In prosecuting the application that matured into 551 patent, Abbott
submitted a declaration purporting to distinguish the above-quoted portion of the ‘382 Patent specification: “[O]ne of skill in the art would have felt that an active electrode comprising [O] e o s t e a t wou ave e t t at a act ve e ect o e co p s g
an enzyme and a mediator would require a protective membrane if it were to be used with a whole blood sample. Therefore, he is sure that one skilled in the art would not read [the ‘382 Patent specification] to teach that the use of t ti b ith h l bl d l i ti ll l a protective membrane with a whole blood sample is optionally or merely
preferred.”
Patent attorney further stated that the “optionally, but preferably” language would have been read as “mere patent phraseology”language would have been read as mere patent phraseology.

Therasense, Inc. v. Becton (Fed. Cir. 2010) (continued) However, during prosecution of European Patent ‘636 (a counterpart to However, during prosecution of European Patent 636 (a counterpart to
the ‘382 Patent, having a virtually identical specification), Abbot argued with respect to the above-quoted portion of the ‘382 Patent specification:p “It is submitted that this disclosure is unequivocally clear. The protective
membrane is optional, however, it is preferred when used on live blood … .”
Abbott did not disclose the arguments made to the EPO to the USPTO gduring prosecution of the application that matured into the ‘551 Patent
Materiality Materiality –– Recent DecisionsRecent Decisions
Therasense, Inc. v. Becton (Fed. Cir. 2010) (continued) District Court (N.D. Ca.) found ‘551 Patent unenforceable( )
Statements made to EPO contradicted statements to PTO in two ways By describing the “optionally, but preferably” language as “unequivocally
clear,” Abbott contradicted its representation that the phrase was mere “patent phraseology” that did not convey a clear meaning to a skilled artisan
Statements to EPO clearly explained that the membranes were merely y p ypreferred for live blood
The contradictory statements were material, and the fact that no credible explanation given for withholding statements suggested i d iintent to deceive
Materiality Materiality –– Recent DecisionsRecent Decisions
Therasense, Inc. v. Becton (Fed. Cir. 2010) (continued) CAFC (Linn, Friedman, Dyk) affirmed CAFC (Linn, Friedman, Dyk) affirmed
Statements to the EPO were material “The ‘unequivocally clear’ statement is tied directly to the optional nature of
the membrane when used with whole blood and other fluids.” Distinguished Abbott’s cited caselaw regarding attorney argument to PTO –
here, contradictory arguments were made in another forum and not disclosed to the PTO
“An applicant’s earlier statements about prior art, especially one’s own prior An applicant s earlier statements about prior art, especially one s own prior art, are material to the PTO when those statements directly contradict the applicant’s position regarding that prior art in the PTO.”
No clear error in determination of intent

Practical SuggestionsPractical Suggestions
Cite existence of related applications to corresponding examinersexaminers
Cite references and office actions from related applications, if material
Document reasons for any decisions not to cite prior art references
Be vigilant about documenting associated applications Consider keeping separate art file references common to
l t d li tirelated applications
