  • So What Facts Are Going To Be The Focus Of The ProV1 Patent Infringement Trial?

    Facts are facts, right? Well, not necessarily. The following are issues of fact that will be litigated in the ProV1 dispute.

    JOINT STATEMENT OF ISSUES OF FACT THAT REMAIN TO BE LITIGATED

    The following factual issues remain to be litigated at trial. To the extent that any issues of law set forth in Exhibits 3 or 4 of the Joint Pre-Trial Order may be considered or include issues of fact, the parties incorporate those portions of Exhibits 3 and 4 herein by reference. The parties incorporate Exhibits 11 and 12 (Brief Statement of Intended Proofs) herein.

    I.    INVALIDITY
    A.    Obviousness

    While obviousness is a legal issue, Acushnet intends to offer evidence on at least the following underlying issues of fact:
    1.    The scope and content of the prior art.
    2.    The level of ordinary skill in the art of the patents-in-suit in 1995.
    3.    The differences, if any, between the claimed inventions of the patents-in-suit and the prior art.
    4.    If Callaway Golf offers evidence of alleged secondary considerations of non-obviousness, Acushnet will offer evidence to rebut such secondary consideration evidence and to demonstrate that there is no nexus between any such alleged secondary considerations and the claimed inventions of the patents-in-suit.
     
    B.    Anticipation
    1.    Whether the asserted claims of the ‘293 patent are anticipated under 35 U.S.C. § 102.
    2.    Whether the asserted claims of the ‘156 patent are anticipated under 35 U.S.C. § 102.
    3.    Whether the asserted claims of the ‘130 patent are anticipated under 35 U.S.C. § 102.
    4.    Whether the asserted claims of the ‘873 patent are anticipated under 35 U.S.C. § 102.
    C.    Other
    1.    Callaway Golf reserves the right to address in rebuttal all issues
    relating to the validity of the patents-in-suit, including:
    (a)    That none of the asserted claims of the patents-in-suit are invalid as anticipated or obvious;
    (b)    whether any suggestion or motivation existed to combine and/or alter prior art to arrive at the inventions set forth in the asserted claims; and
    (c) the extent of objective indicia of nonobviousness of the inventions set forth in the asserted claims, including: (i) commercial success of products covered by any of the asserted patent claims; (ii) a long felt, unmet need in the art that was satisfied by the invention; (iii) the failure by others to make the invention; (iv) copying of the invention by others; (v) initial skepticism of the invention by others; (vi) praise of the invention by others. Callaway Golf will also show that there is a nexus between the secondary considerations and the claimed inventions of the patents-in-suit.
    II. DAMAGES
    1.    The amount of damages, if any, in the form of lost profits due to Callaway Golf as a result of Acushnet Company’s infringement.

    2.    The amount of damages, if any, in the form of a royalty due to Callaway Golf as a result of Acushnet Company’s infringement.

    Sounds like an interesting trial!

  • Let’s Look at Some Facts that Callaway and Acushnet Agree Upon Regarding the Titleist ProV1 Golf Ball Patent Litigation

    In patent litigation it is generally pretty hard for the parties to agree upon anything. Fortunately, a court can be pretty persuasive in forcing the parties to state the facts that they cannot fight about. Here are a few facts that Callaway and Acushnet have agreed upon in the ProV1 litigation.


    STATEMENT OF FACTS WHICH ARE ADMITTED AND REQUIRE NO PROOF

    Plaintiff and Defendant stipulate to the following admitted facts that require no proof:

    1.    Plaintiff Callaway Golf Company (“Callaway Golf”) is a corporation organized and existing under the laws of the State of Delaware, having a principal place of business in Carlsbad, California.

    2.    Callaway Golf is the parent company of Callaway Golf Ball Operations, formerly known as The Top-Flite Golf Company (collectively, “Top-Flite”), which is a corporation organized and existing under the laws of the State of Delaware, having a principal place of business in Chicopee, Massachusetts.

    3.    Defendant Acushnet Company (“Acushnet”) is a corporation organized and existing under the laws of the State of Delaware, having a principal place of business in Fairhaven, Massachusetts.

    4.    Acushnet is a wholly-owned operating company of Fortune Brands, Inc. (“Fortune Brands”).

    5.    Fortune Brands is a publicly-traded corporation organized and existing under the laws of the State of Delaware.

    6.    United States Patent No. 6,210,293 (“the ’293 patent”) entitled “Multi-Layer Golf Ball” issued on April 3, 2001.

    7.    United States Patent No. 6,503,156 (“the ’156 patent”) entitled “Golf Ball Having Multi-Layer Cover With Unique Cover Characteristics” issued on January 7, 2003.

    8.    United States Patent No. 6,506,130 (“the ’130 patent”) entitled “Multi-Layer Golf Ball” issued on January 14, 2003.

    9.    United States Patent No. 6,595,873 (“the ’873 patent”) entitled “Multi-Layer Golf Ball” issued on July 22, 2003.

    10.    Michael J. Sullivan is the sole named inventor on the ’293, ’156, ’130, and ’873 patents (collectively “the patents-in-suit”).

    11.    United States Patent 4,274,637 (“Molitor ‘637”), entitled “Golf ball having cellular cover,” issued on June 23, 1981.

    12.    United States Patent 4,431,193 (“Nesbitt”), entitled “Golf ball and method of making same,” issued on February 14, 1984.

    13.    United States Patent 4,674,751 (“Molitor ‘751”), entitled “Golf ball having improved playability properties,” issued on June 23, 1987.

    14.    United States Patent 5,314,187 (“Proudfit”), entitled “Golf ball with improved cover,” issued on May 24, 1994.

    15.    United States Patent 5,334,673 (“Wu”), entitled “Polyurethane golf ball,” issued on August 2, 1994.
     
    16.    The effective priority date of the ‘293, 156, and ‘873 patents is November 9, 1995.

    17.    The effective priority date of the ‘130 patent is October 13, 1995.

    18.    Callaway Golf currently owns U.S. Patent Nos. 6,210,293; 6,503,156; 6,506,130; and 6,595,873 (“the patents-in-suit”) and has owned them at all times pertinent to this case.

    19.    Acushnet’ s Titleist ProV1 golf balls are covered by and infringe:
    Claims 1, 4 and 5 of U.S. Patent No. 6,210,293; Claims 1, 2 and 3 of U.S. Patent No. 6,503,156; Claim 5 of U.S. Patent No. 6,506,130; and Claims 1 and 3 of U.S. Patent 6,595,873.

    20.    Acushnet’s Titleist Pro V1x and Pro V1* golf balls are covered by and infringe:
    Claims 4 and 5 of U.S. Patent No. 6,210,293; Claims 1, 2 and 3 of U.S. Patent No. 6,503,156; Claim 5 of U.S. Patent No. 6,506,130; and Claims 1 and 3 of U.S. Patent 6,595,873.

    21. Due to manufacturing variations, some small percentage of these golf balls may fall outside the claimed hardness range for the outer cover layer, and therefore, as a compromise, the parties stipulate and agree that 95% of all golf balls of each three types are covered by and infringe the claims identified above.

  • The Proposed Jury Instructions for the ProV1 Patent Litigation Trial

    Yesterday we looked at the jointly proposed voir dire for the ProV1 patent infringement trial; today let’s look at the jointly proposed jury instructions.

    PRELIMINARY INSTRUCTIONS

    Members of the jury:

    Now that you have been sworn, I have the following preliminary instructions for guidance on your role as jurors in this case.

    The Parties

    This is a case arising under the patent laws of the United States. The plaintiff is Callaway Golf Company, which I will refer to as "Callaway." The defendant is Acushnet Company, which I will refer to as "Acushnet." Callaway and Acushnet are companies engaged in the design, development, marketing, and sale of golf balls.

    Callaway is the owner of the United States patents at issue in this case. There are four patents at issue: U.S. Patent No. 6,506,130, which I will refer to as "the '130 patent"; U.S. Patent No. 6,503,156, which I will refer to as "the '156 patent"; U.S. Patent No. 6,210,293, which I will refer to as "the '293 patent"; and U.S. Patent No. 6,595,873, which I will refer to as "the '873 patent." I may refer to these patents collectively as "the patents in suit," or, alternatively, as "the Callaway patents." Copies of these patents have been given to you along with these preliminary instructions.

    You will be given notebooks which have a copy of these instructions, copies of the patents, and have paper for you to take notes if you choose to during the trial.

    The parties have stipulated that Acushnet infringes claims 1, 4, and 5 of the '293 patent, claims 1, 2, and 3 of the '156 patent, claim 5 of the '130 patent, and claims 1 and 3 of the '873 patent. Therefore, you will not be asked to determine the issue of infringement. However, Acushnet asserts that each of the patents in suit is invalid and, therefore, you will be asked to review the validity of each of these patents.

    Callaway denies that the patents in suit are invalid and seeks damages for infringement of the patents by the following golf balls under Acushnet's Titleist brand: the Titleist Pro V1, the Titleist Pro V1 x, and the Titleist Pro V1*.
     
    Burden Of Proof

    [CALLAWAY'S PROPOSED INSTRUCTION]

    This is a civil case in which Callaway is asking for damages for Acushnet's infringement. Callaway has the burden of establishing its entitlement to damages by what is called a preponderance of the evidence. That means Callaway has to produce evidence which, when considered in light of all of the facts, leads you to believe that what Callaway claims is more likely true than not. To put it differently, if you were to put Callaway and Acushnet's evidence on the opposite sides of a scale, the evidence supporting Callaway's claims would have to make the scales tip somewhat on its side.

    Acushnet contends that the patents in suit are invalid. A patent, however, is presumed to be valid. Accordingly, Acushnet has the burden of proving that each of the patents in suit are invalid by clear and convincing evidence. Clear and convincing evidence is evidence that produces an abiding conviction that the truth of a factual contention is highly probable. Proof by clear and convincing evidence is thus a higher burden than proof by a preponderance of the evidence.

    Those of you who are familiar with criminal cases will have heard the term "proof beyond a reasonable doubt." That burden does not apply in a civil case and you should, therefore, put it out of your mind in considering whether or not Callaway and Acushnet have met their respective burdens of proof in this case.

    [ACUSHNET'S PROPOSED INSTRUCTION]

    This is a civil case in which Acushnet contends that the patents in suit are invalid. Acushnet has the burden of proving that each of the patents in suit are invalid by clear and convincing evidence.[FN1] Clear and convincing evidence is evidence that produces an abiding conviction that the truth of a factual contention is highly probable.

    Callaway has the burden of proving damages by what is called a preponderance of the evidence. A "preponderance of the evidence" means that the patent owner has to produce evidence which, when considered in the light of all the facts, leads you to believe that what the patent owner alleges is more likely true than not.

    Those of you who are familiar with criminal cases will have heard the term "proof beyond a reasonable doubt." That burden does not apply in a civil case and you should, therefore, put it out of your mind in considering whether or not Callaway and Acushnet have met their respective burdens of proof in this case.

    Duty Of Jury

    It will be your duty to find what the facts are from the evidence as presented at trial. You, and you alone, are the judges of the facts. You will have to apply those facts to the law as I will instruct you at the close of evidence. You must follow that law whether you agree with it or not.

    You are the judges of the facts. Iwill decide which rules of law apply to this case. Nothing I say or do during the course of the trial is intended to indicate what your verdict should be.

    Evidence

    The evidence from which you will find the facts will consist of the testimony of witnesses, and documents and other things admitted into evidence. In addition, the evidence may include certain facts as agreed to by the parties or as I instruct you.

    Certain things are not evidence.

    1.    Statements, arguments and questions by lawyers are not evidence. Objections to questions are not evidence. Lawyers have an obligation to their clients to make an objection when they believe testimony or exhibits being offered into evidence are not admissible under the rules of evidence. You should not be influenced by a lawyer's objection or by my ruling on the objection. If I sustain or uphold the objection, and find the matter is not admissible, you should ignore the question or other item of evidence. If I overrule an objection and allow the matter in evidence, you should consider the testimony or other item of evidence as you would any evidence. If I instruct you during the trial that some item of evidence is admitted for a limited purpose, you must follow that instruction and consider the evidence for that purpose only. I will instruct you further during the trial if this happens.

    2.    Anything you see or hear outside the courtroom is not evidence and must be disregarded. You are to decide this case solely on the evidence presented here in the courtroom.

    In judging the facts, it will be up to you to decide which witnesses to believe, which witnesses not to believe, and how much of any witness's testimony to accept or reject.

    Conduct Of The Jury

    Now, a few words about your conduct as jurors.

    Although you are not to talk about the case with anyone else, you are permitted to talk to each other, when everyone is in the jury room, about the technology at issue in this case. You may write questions down and give them to Nicole, my courtroom deputy.
     
    She will give the questions to me and I will pass them along to the attorneys, who may or may not try to incorporate your questions into their examinations.

    Even though you may talk to each other about the technology, you should not reach any conclusions as to the issues presented until all the evidence is in and you have been given your final instructions.
    Finally, you must only consider the evidence presented in the courtroom. Do not read or listen to anything touching on this case that is not admitted into evidence. By that I mean, if there may be a newspaper article or radio or television report relating to this case, do not read the article or watch or listen to the report. In addition, do not try to do any independent research or investigation on your own on matters relating to this case.

    The proceedings during trial will be transcribed by court reporters; however, it is not the practice of this Court to make the trial transcripts available to jurors. You must rely on your own recollection of what testimony was presented and how credible that testimony was.

    If you wish, you may take notes in the binders we have provided. The binders will be collected each time you leave the courtroom. Keep in mind that your notes are for your own personal use - they are not to be given or read by anyone else.

    Finally, please wear your juror identification tags everyday, so that the parties can avoid engaging you in conversation, thereby bringing your impartiality into question.

    Course Of The Trial

    The trial will now begin. The attorneys have three opportunities to talk to you during the trial. The first opportunity is the opening statement. During the opening statements, the attorneys will introduce their respective stories to you. As I've already instructed, however, what the lawyers say is not evidence. It will be up to you to determine whether the evidence - the testimony of the witnesses and the admitted documents - supports what the lawyers say in their opening statements. The second opportunity that the lawyers have to talk to you is during transition statements. Lawyers are permitted to make transition statements whenever they call a witness to the stand, to introduce the witness and to briefly explain the relevance of the witness's anticipated testimony. Finally, after all the evidence is in, the lawyers will offer closing arguments to summarize and interpret the evidence for you, and to tie the evidence to their story. I will then give you instructions on the law and describe for you the matters you must resolve.

    You will then retire to the jury room to deliberate on your verdict.

    You should generally expect that we will start the trial each morning at 9:30 a.m. and finish at 4:30 p.m., with two 15-minute breaks (morning and afternoon), and one half-hour break for lunch. As I said earlier, I time my civil trials, meaning each party is given a certain number of hours in which to present its evidence. This assures that trials will be completed on a predictable basis. This system can only work, however, if you, as jurors, report to the courtroom on a punctual basis as well.

    FN1 Acushnet submits that the jury should not be instructed as to the presumption of validity. The presumption underlies the requirement that invalidity be proven by clear and convincing evidence, hence reciting the presumption in addition to the burden of proof is confusing and redundant. Patent Case Management Judicial Guide § 8.1.2.2.2.1 at 8-15 (Fed. Jud. Ctr. 2009) ("[lIt is now generally agreed that juries should be instructed as to the higher burden of proof required to prove invalidity, but should not be told that there is a presumption of validity, which would be redundant and likely confusing."); Fed. Cir. Bar Ass'n Model Patent Jury Instructions, Note to 10.1 ("In light of the procedural role of the presumption of validity, instruction the jury on the presumption in addition to informing it of the clear and convincing burden of proof may cause jury confusion as to its role in deciding validity."); see also American Intellectual Prop. Law Ass'n Model Patent Jury Instructions (omitting any reference to presumption of validity); Chiron Corp. v. Genentech, Inc., 363 F.3d 1247, 1258-59 (Fed. Cir. 2004) (approving district court's omission of the presumption of validity instruction).

    Callaway Golf respectfully responds that the presumption of validity is statutory, see 35 U.S.C. § 282, and merely instructing the jury on the burden of proof is insufficient because it does not instruct the jury why that burden is required - to overcome the statutory presumption that the Patent Office did its job. See American Hoist & Derrick Co. v. Sowa & Sons, Inc., 725 F.2d 1350, 1359 (Fed. Cir. 1984); Brooktree Corp. v. AMD, 977 F.2d 1555, 1574 (Fed. Cir. 1992). This Court routinely instructs juries on the presumption of validity, (see D. Del. Model Patent Jury Instruction 1.3), and no Federal Circuit opinion has ever shed any doubt on that practice. Further, Callaway Golf notes that this instruction was given during the first trial (see D.I. 394 at 3), and in fact Acushnet itself actually proposed instructing the jury on the presumption, (see D.I. 389 at p.26), waiving this argument. See Christianson v. Colt Indus. Operating Corp., 486 U.S. 800, 815-16 (1988); Amado v. Microsoft Corp., 517 F.3d 1353, 1360 (Fed. Cir. 2008); EngelIndus., Inc. v. Lockformer Co., 166 F.3d 1379, 1382-84 (Fed. Cir. 1999).
    Interesting stuff. I suspect that some of you, like me, would pay to be on the jury.

  • Gearing Up for the Biggest Golf Patent Infringement Trial in History

    Jury selection begins this Friday for the big ProV1 trial. This could be the jury that awards the largest amount of damages in golf history; but it could also be the jury that awards nada. In this case it isn’t very often that Callaway and Acushnet agree on anything, therefore let’s take a look at their jointly proposed voir dire designed to screen prospective jurors.
    PROPOSED VOIR DIRE
    Good morning, ladies and gentlemen. I am Judge Robinson, and I will be presiding over the trial for which a jury is about to be drawn in the case captioned Callaway Golf Co. v. Acushnet Co. Briefly stated, this is an action arising under the patent laws of the United States involving golf ball patents.

    The trial may last up to 5 days. I time my trials, so the attorneys have to complete their trial presentations within these limits. However, jury deliberations may require you to be present longer than the scheduled 5 days. Our trial days will run approximately from 9:30 a.m. to 4:30 p.m.

    In light of this brief summary, I will now ask you certain questions, the purpose of which is to: (1) enable the court to determine whether or not any prospective juror should be excused for cause; and (2) enable counsel for the parties to exercise their individual judgment with respect to peremptory challenges, that is, challenges for which no reason need be given by counsel. If any of you answer any question "yes," please stand up and, upon being recognized by the court, state your juror number. When I have concluded asking all the questions, we will call you individually to the bench to speak with you about your affirmative response or responses.

    12.    Do you have any strong opinions about a patent granting exclusive rights to the inventors or their employer?

    13.    [CALLAWAY PROPOSED QUESTION] Do you believe it would be wrong for someone to profit from his invention or discovery? FN1 – (Callaway Golf notes that this question was asked during the first voir dire, and respectfully requests that it be asked again. (See D.I. 377, Question 13). Acushnet objects to this question.

    14.    Have you, any member of your immediate family, or anyone close to you ever worked for a golf equipment manufacturer, or been employed in the golf industry, such as golf courses or retail stores selling golf equipment?

    15.    Have you ever used products relating to the sport of golf that you know to be made by Callaway Golf Company or Acushnet Company, including, but not limited to, golf products sold under the brand names Titleist, Cobra, FootJoy, Callaway, Top-Flite, Spalding, CTU 30, Ben Hogan, Strata, Tour Ace or Pro V1?

    19.    Do you know of any other matter which you believe should be called to the Court's attention as having some bearing upon your qualifications or ability to sit as a juror, or which you think may prevent you from rendering a fair, unbiased and impartial verdict based solely upon the evidence and my instructions as to the law?

    What are your thoughts? Are these questions good enough to identify the crazies or those with bias?

    I wonder if one side or the other is better off having jurors that are golfers? Interesting question that Callaway and Acushnet have probably studied in detail. What about the USGA question? Would you want people associated with the USGA on the jury, or excluded from it?

  • Is This Club Manufacturing Method Crazy or Beautifully Genius?

    A patent issued this week directed to a golf club manufacturing technique that is rather interesting. The patent is USPN 7,670,532 titled “Golf Club Head and Method of Making the Same,” and describes the invention as:

    A golf club head and a method of making a golf club head are disclosed. The method provides for winding a single continuous filament multiple times about a soluble core. The wound core is located in a mold and pressure coated with a pure or non-continuous fiber filled resin. The resin is allowed to cure to form a filament and resin shell about the core. The soluble core is removed leaving the continuous filament in the shell.

    The patent explains:

    It is an object of the present invention to overcome the disadvantages inherent to the above described and traditional methods and resulting structures of club heads, and to provide a new head design as well as a new method of manufacturing such head.

    Thus, one of the more specific objects of the invention is to provide a manufacturing method enabling a more efficient new head structure to be obtained, especially as regards distribution of mass, durability, and finishing quality. The method according to the invention is particularly adapted to the large scale production of elements requiring a minimum number of operations to produce what might be considered a complex yet highly advantageous golf club head.

    Thus, according to the invention, a method of manufacturing a golf club is disclosed. The method is comprised of the following steps. A single continuous filament is wound multiple times about a soluble core. The wound core is then located in a mold. The wound core is then pressure coated with a resin in the mold. The resin disperses among the filament windings. The resin is allowed to cure and form a filament and resin shell about the core. The soluble core is then removed from the shell while the continuous filament is retained within the shell.

    The shell has an inside surface and an outside surface. The inside surface defines a substantially hollow interior portion and the inside surface has a plurality of ribs that extend into the interior portion. The ribs and the shell are substantially comprised of the resin and the single continuous filament located within the resin.

    So, it that crazy or genius?
