    I. OVERVIEW

    InNautilus, Inc. v. Biosig Instruments, Inc., Supreme Court No. 13-369,

    opinion below, Biosig Instruments, Inc. v. Nautilus, Inc., 715 F.3d 891, 900 (Fed.

    Cir. 2013)(Wallach, J.), petitioner reawakens the ghost of United Carbon Co. v.

    Binney & Smith Co., 317 U.S. 228 (1942), the last major Supreme Court case

    where claims were invalidated for indefiniteness under what today is 35 USC

    112(b).

    Under the Federal Circuit case law even a claim deliberately drafted with

    ambiguities to cloud the true scope of protection is saved from invalidity unless the

    claim is insolubly ambiguous. Petitioner asks the Supreme Court in the first

    Question Presented:

    Does the Federal Circuits acceptance of ambiguous patent claims with multiple

    reasonable interpretationsso long as the ambiguity is not insolubleby a courtdefeat the statutory requirement of particular and distinct patent claiming?

    It is likely that the Supreme Court will reverse the Federal Circuit inNautilus.

    Thats the easy part. Then, the harder points. What standardif anyshould be

    set for determining claim particularity? What test will the Federal Circuit create for

    claim particularity within the ambit of whatever guidance is given by the Supreme

    Court?

    The starting point is a recognition that there are two competing elements.

    First, the system must permit a certain claiming latitude to inventors, given the

    difficulties of language to precisely define the scope of technological innovation.

    Second, of course, there is the need for clear boundaries of protection to foster

    competition and encourage future innovation. See III,Public Policy: Two Sides

    of the Coin.

    The Federal Circuit has developed a unique test for determining whether the

    patentee has provided claims with sufficient particularity: If there is an ambiguity

    in the claim the threshold of invalidity is reached only if the claim is insolubly

    ambiguous. To the contrary, under Commonwealth case law dating back nearly

    one full century and as manifested in Canadian opinions, there is a much lower

    threshold: Claims are invalidated where they are avoidablyambiguous. See

    III, Avoidably (versus Insolubly) Ambiguous Claiming

    II. PUBLIC POLICY: TWO SIDES OF THE COIN

    There are manifestly two sides to the coin, both important. On the one hand,

    it remains important for the judicial system to encourage innovation by providing

    relatively certain patent protection for the inventor freeas much as possible

    from arcane rules and procedural obstacles to sustain such patent rights. The

    Court inExxon Researchjustifies its obviously pro-patentee bias by the statement

    that [b]y finding claims indefinite only if reasonable efforts at claim construction

    prove futile, we accord respect to the statutory presumption of patent validity,see

    N. Am. Vaccine, Inc. v. Am. Cyanamid Co., 7 F.3d 1571, 1579 (Fed. Cir. 1993),

    andwe protect the inventive contribution of patentees, even when the drafting of

    their patents has been less than ideal.Exxon Research & Eng'g Co. v. United

    States, 265 F.3d 1371, 1375 (Fed. Cir. 2001)(emphasis added).The other side of the coin is seen from nineteenth century case law that

    focuses on the need for clear claim boundaries to fosterfurther innovation.

    The current standard for patent claims under what is now 35 USC 112(b)

    can be traced to the second half of the nineteenth century. Then, the United States

    developed a mandatory system of patent claims to define the metes and bounds of

    protection.

    The policy considerationsand the need to point out clear boundaries of

    protection through such claimswas pointed out inMerrill v. Yeomans,a

    contemporaneous opinion of the Supreme Court that explains this evolution of the

    law:

    The growth of the patent system in the last quarter of a century in this country has

    reached a stage in its progress where the variety and magnitude of the interests

    involved require accuracy, precision, and care in the preparation of all the papers

    on which the patent is founded. It is no longer a scarcely recognized principle,

    struggling for a foothold, but it is an organized system, with well-settled rules,

    supporting itself at once by its utility, and by the wealth which it creates and

    commands. The developed and improved condition of the patent law, and of the

    principles which govern the exclusive rights conferred by it, leave no excuse for

    ambiguous language or vague descriptions. The public should not be deprived of

    rights supposed to belong to it, without being clearly told what it is that limits these

    rights. The genius of the inventor, constantly making improvements in existing

    patents, a process which gives to the patent system its greatest value,should

    not be restrained by vague and indefinite descriptions of claims in existing patents

    from the salutary and necessary right of improving on that which has already been

    invented. It seems to us that nothing can be more just and fair, both to the patentee

    and to the public, than that the former should understand, and correctly describe,

    just what he has invented, and for what he claims a patent.

    III. AVOIDABLY (VERSUS INSOLUBLY) AMBIGUOUS CLAIMING

    The two sides to the public policy debate are also recognized in the

    Commonwealth countries. The Commonwealth countries have recognized both

    the need for clear claim boundaries to foster competition and future research while

    also honoring the rights of the inventor to gain reasonable protection where it is

    difficult or impossible to draft claims with the most precise boundaries.

    Whereas the Federal Circuit will invalidate a claim for violation of the

    definiteness requirement of 35 USC 112(b) only if the claim is insolubly

    ambiguous, the Commonwealth will invalidate a claim under a lower barwhere

    the claim is avoidably ambiguous. Pfizer Canada Inc. v. Canada (Minister of

    Health), [2005] F.C.J. No. 2155 (Federal Court of Canada 2005)(Hughes,

    J.)(quotingNatural Colour Kinematograph Company Limited v Bioschemes

    Limited(1915) 32 RPC 256, 266 (1915)(Loreborn, J.)).

    The avoidably ambiguoustest has three elements as explained by Judge

    Hughes in the citedPfizer Canada case:

    [1] [L]anguage whichis avoidably obscure or ambiguous [invalidates the claim]

    whether the defect be due to design, or to carelessness or to want of skill.

    [2] Where the invention is difficult to explain, due allowance will, of course, be

    made, for any resulting difficulty in the language.

    [3] But nothing can excuse the use of ambiguous language when simple language

    can easily be employed, and the only safe way is for the patentee to do his best tobe clear and intelligible."

    The Canadian (Commonwealth) approach is explained in greater detail in

    the Appendix, an earlier paper entitled The Lord Loreborn Test For 112(b)

    Indefiniteness: An Alternative to Insolubly Ambiguous

    IV. CONCLUSION

    To the extent that the Court overturns the insolublyambiguous test of the

    Federal Circuit, it is important that a balanced test is created that protects the

    inventor from the difficulties of claim language. Consideration should be given to

    the approach taken by Judge Hughes in Canada that invalidates a claim for the

    lower bar of being avoidablyambiguous.

    I. OVERVIEW

    Judge Roger Hughes quotation of the Lord Loreborn test for claim

    indefiniteness is only one of the more recent opinions to restate a nearly century

    old standard in Commonwealth countries to determine when a claim is invalid as

    indefinite. Without benefit of a test of this nature, the United States struggles to

    determine when a claim should be thrown out as indefinite; fuzzy boundaries

    encourage sloppy claim drafting to the detriment of the patent community.

    Instead, the Federal Circuit sanctions clearly ambiguous language as long as theambiguity is not insoluble.

    The Supreme Court has not directly addressed claim ambiguity in the sense

    of fatal indefiniteness for the more than seventy years since of United Carbon Co.

    v. Binney & Smith Co., 317 U.S. 228 (1942). It is inevitable that at some point in

    the not too distant future the Court will grant certiorari to focus upon whether the

    Federal Circuit test should remain the law. The only question about grant of

    certiorari is when this will happen. The next opportunity for the Court to grant

    review is Friday, January 10th, at its Conference when a vote may be expected as

    to whether to grant review inNautilus, Inc. v. Biosig Instruments, Inc., Supreme

    Court No. 13-369, opinion below, Biosig Instruments, Inc. v. Nautilus, Inc., 715

    F.3d 891, 900 (Fed. Cir. 2013)(Wallach, J.), where Petitioner asks whether the

    Federal Circuits acceptance of ambiguous patent claims with multiple reasonable

    interpretationsso long as the ambiguity is not insoluble by a courtdefeat the

    statutory requirement of particular and distinct patent claiming?

  • 8/13/2019 Nautilus Jan 13

    APPENDIX: Wegner, TheLord LorebornTest

    3

    The United States has two different lines of case law for the interpretation of

    patent claims with respect to indefiniteness under 35 USC 112(b). The Supreme

    Court has a zone of uncertainty test while the Federal Circuit is seemingly more

    forgiving of patentee draftsmanship mistakes by concluding that claims are fatally

    indefinite only if insolubly ambiguous. See II, Clashing Analytical Metrics for

    Claim Analysis.

    Only one court has cited with approval the middle ground solution of nearly

    a full century ago inNatural Colour Kinematograph that asks whether claimlanguage is avoidablyobscure or ambiguous.Natural Colour Kinematograph

    Company, 32 RPC at 266: It is no excuse that the drafting error was due to

    carelessness or to want of skill; the test was relied upon in an early Ninth Circuit

    opinion. Id. See III, The Three Part Test of Lord Loreborn.

    A further difficulty with the insolubly ambiguous test for invalidity is that

    patentees are encouraged to draft claims that come just short of meeting that

    standard, yet which are unnecessarily vague and indefinite to the detriment of

    competitors. See IV, Insolubly Ambiguous Test Invites Gamesmanship.

    II. CLASHING ANALYTICAL METRICS FOR CLAIM ANALYSIS

    The United States currently has two different lines of case law to determine

    whether a claim is fatally indefinite under what is now 35 USC 112(b). On the

    one hand, there is the United Carbon line of case law that focuses upon the zone

    of uncertainty created by ambiguities in the claim language, whereas the Federal

    Circuit follows theDatamize test as to whether a claim is insolubly ambiguous.

    United Carbon, supra;Datamize, LLC v. Plumtree Software, Inc., 417 F.3d 1342,

    1347 (Fed. Cir. 2005).

    A. The Supreme Court Zone of Uncertainty Test

    The Supreme Court in United Carbon set forth a zone of uncertainty test

    for determining whether a claim is fatally indefinite:

    [T]helimits of a patent must be known for the protection of the patentee, the

    encouragement of the inventive genius of others and the assurance that the subjectof the patent will be dedicated ultimately to the public.[General Elec. Co.v.Wabash Appliance Corp., 304 U.S. 364, 369 (1938).] Otherwise, a zone of

    uncertaintywhich enterprise and experimentation may enter only at the risk ofinfringement claims would discourage invention only a little less than unequivocal

    foreclosure of the field,United Carbon Co.v.Binney & Smith Co., 317 U.S. 228,236 (1942), and the public [would] be deprived of rights supposed to belong to it,

    without being clearly told what it is that limits these rights.Merrillv. Yeomans, 94U.S. (4 Otto) 568, 573 (1877).Markman v. Westview Instruments, 517 U.S. 370,

    390 (1996)(dictum)(emphasis added).

    The quoted passage from United Carbon is from a longer statement:

  • 8/13/2019 Nautilus Jan 13

    11/18

    APPENDIX: Wegner, TheLord LorebornTest

    5

    The statutory requirement of particularity and distinctness in claims is met only

    when they clearly distinguish what is claimed from what went before in the art andclearly circumscribe what is foreclosed from future enterprise. A zone of

    uncertainty which enterprise and experimentation may enter only at the risk ofinfringement claims would discourage invention only a little less than unequivocal

    foreclosure of the field. Moreover, the claims must be reasonably clear-cut to

    enable courts to determine whether novelty and invention are genuine. * * * While

    we do not find it necessary to consider questions of novelty and invention, in theview we take of the claims in suit, a mere reading of prior art patents shows how, if

    they are read with the liberality and inclusiveness claimed for those in suit, theydescribe products, if not identical, at least of confusing similarity. Whether the

    vagueness of the claim has its source in the language employed or in the somewhat

    indeterminate character of the advance claimed to have been made in the art is notmaterial. An invention must be capable of accurate definition, and it must beaccurately defined, to be patentable. Cf.General Electric Co. v. Wabash [Appliance

    Corp., 304 U.S. 364, 372-73 (1938)] United Carbon, 317 U.S. at 236-37(footnote omitted).

    B. The More Liberal Federal Circuit Approach

    The Federal Circuit sustains or denies ambiguous claims under a test

    expressed inDatamize: A claim is indefinite only when it is not amenable to

    construction or insolubly ambiguous. Star Scientific, Inc. v. R.J. Reynolds

    Tobacco Co., 537 F.3d 1357, 1371 (Fed. Cir. 2008)(quotingDatamize, LLC v.

    Plumtree Software, Inc., 417 F.3d 1342, 1347 (Fed. Cir. 2005)).

    The insolubly ambiguous test was recently explained in Teva v. Sandoz:

  • 8/13/2019 Nautilus Jan 13

    12/18

    APPENDIX: Wegner, TheLord LorebornTest

    6

    To prove indefiniteness [under the Federal Circuit insolubly ambiguous test],

    an accused infringer must demonstrate by clear and convincing evidence that oneskilled in the relevant art could not discern the boundaries of the claim based on

    the claim language, the specification, the prosecution history, and the knowledge inthe relevant art.

    Teva Pharms. USA, Inc. v. Sandoz, Inc.,723 F.3d 1363, 1367 (Fed. Cir.2013)(Moore, J.)(quoting Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355,1366 (Fed. Cir. 2011)).

    As noted in the opinion of the Federal Circuit in theNautilis case now at the

    Supreme Court, a claim may pass 112(b) muster even where its scope is notplain on [its] face, the task to resolve the scope is formidable and requires

    some experimentation andwhere in the end reasonable persons will disagree:

    [W]e have not insisted that claims be plain on their face in order to avoid a

    determination of invalidity for indefiniteness. Exxon [Research & Eng'g Co. v.

    United States, 265 F.3d 1371, 1375 (Fed. Cir. 2001)]. If the meaning of the claim

    is discernible, even though the task may be formidable and the conclusion may be

    one over which reasonable persons will disagree, we have held the claimsufficiently clear to avoid invalidity on indefiniteness grounds.Id. In addition,

    ** * the fact that some experimentation may be necessary to determine the scope

    of the claims does not render the claims indefinite.Id. at 1379.

    Biosig Instruments, Inc. v. Nautilus, Inc., 715 F.3d 891, 901-02 (Fed. Cir.

    2013)(Wallach, J.)

    III. THE THREE PART TEST OF LORD LOREBORN

    The noted Canadian jurist, Roger Hughes, points to [t]hebedevilling of the

    law by the ghosts of the[ ] earlier, pre-claim, cases [which] is evident in the cri de

    coeurof Lord Loreburn inNatural Colour Kinematograph Co. Ltd. v. Bioschemes

    Ltd, (1915) 32 R.P.C. 256, 266 (H.L.) where he speaks of counsel shaping and re-

    shaping a claim with references to the specification and other evidence[.]Pfizer

    Canada Inc. v. Canada (Minister of Health),[2005] F.C.J. No. 2155 (Federal

    Court of Canada 2005)(Hughes, J.).

    In essence, Lord Loreborn sets forth a three part test to determine whether a

    claim is fatally ambiguous:

    It is the duty of patentee to state clearly and distinctly, either in direct words or by

    clear and distinct reference, the nature and limits of what he claims.

    [1] If [the patentee] uses language which, when fairly read, is avoidably

    obscure or ambiguous, the Patent is invalid[.]

    [2] [The conclusion of invalidity is reached] whether the defect be due todesign,

    or to carelessness or to want of skill.

    [3] Where the invention is difficult to explain, due allowance will, of course, bemade for any resulting difficulty in the language. But nothing can excuse the use of

    ambiguous language when simple language can easily be employed, and the onlysafe way is for the patentee to do his best to be clear and intelligible.

    Judge Hughes is far from a voice crying in the patent wilderness. Several

    jurists have recited the test of Lord Loreborn. Imperial Chemical Industries v.

    Montedison (UK) Ltd, [1995] RPC 449 (Court of Appeal 1995)(UK)(Stuart-Smith,

    J.); Wake Forest University Health Sciences v. Smith & Nephew Pty Ltd, 92 I.P.R.

    496, 822 (Federal Court of Australia 2011)(Dodds-Streeton, J.).

    As pointed out by the Ninth Circuit in Otis Elevator, [i]t is [the]

    delimitation of the extent of the monopoly which is the function of the modern

    claim.Avoidable ambiguityin the delimitation may, under the modern Englishcases, invalidate the entire patent. Otis Elevator Co. v. Pacific Finance Corp., 68

    F.2d 664, 667 (9th Cir. 1934)(citingNatural Colour Kinematograph)(emphasis

    added).

    IV. INSOLUBLY AMBIGUOUS TEST INVITES GAMESMANSHIP

    The insolubly ambiguous test encourages gamesmanship in claim drafting

    where patentees are able to gain claims that would be invalid under the Lord

    Loreborn test but which can be figured out with difficulty and thus be sustained

    because they are not insolubly ambiguous. The routine use even today of

    means-defined elements in claims where there is only vague support for such

    elements in the specification is a major example: What other reason does a

    patentee have to employ a means-defined element in his claims.

    It is one thing to give a pass to the patentee who has difficulty drafting

    claims where the invention is difficult to explain as noted by Lord Loreburn.

    But it is entirely a different situation where the patentee is able to craft clear claims

    but chooses instead to game the system:

    * * * I think this Patent is bad from ambiguity in the Specification. There seems tobe some danger of the well known rule of law against ambiguity being in practice

    invaded. Some of those who draft Specifications and Claims are apt to treat thisindustry as a trial of skill, in which the object is to make the Claim very wide upon

    one interpretation of it, in order to prevent as many people as possible from

    competing with the patentee's business and then to rely upon carefully preparedsentences in the Specification which, it is hoped, will be just enough to limit theClaim within safe dimensions if it is attacked in Court. This leads to litigation as to

    the construction of Specifications, which could generally be avoided if at the outseta sincere attempt were made to state exactly what was meant in plain language.

    The fear of a costly law suit is apt to deter any but wealthy competitors fromcontesting a Patent. This is all wrong. It is an abuse which a Court can prevent,

    whether a charge of ambiguity is or is not raised on the Pleadings, because itaffects the public by practically enlarging the monopoly, and does so by a kind of

    pressure which is very objectionable. * * *

    I cannot see what purpose there could have been using the roundabout languagehere employed, which has provoked so much argumentative subtlety and taken up

    so much time, unless the object was to hold in reserve a variety of constructions foruse if the Patent should be called in question, and in the meantime to frighten off

    those who might be disposed to challenge the Patent.

    V. CONCLUSION

    Given that it has been more than seventy years since United Carbon, grant

    of certiorari inNautilis v. Biosig is very far from a certain thing. What is clear,

    however, is that at some point in the coming years the Court will revisit United

    Carbon if the insolubly ambiguous test goes forth, unabated.

    To the extent that certiorari is denied inNautilis v. Biosig this will give the

    Federal Circuit additional time to work out a better solution than the extreme testof whether a claim is insolubly ambiguous before dropping the invalidity

    hammer.
