If Prior Art Include All Element Except One Still Anticipation
Anticipation is a basic concept in patent law. On its face the concept is simple—if a single prior fine art reference teaches every chemical element of a claim in the proper context, then the claim is not patentable, i.e., it is anticipated by the prior art reference. Anticipation is easy enough to establish if the prior art expressly sets forth each of the elements of the claims. However, more interesting issues of proof arise when one or more elements of the claims are not expressly stated in the prior art, but following the prior art necessarily yields the missing elements of the claim.
The courts developed the concept of inherent anticipation to deal with the situation where an issued patent covers bailiwick matter that already exists in the prior art but is not expressly taught or fifty-fifty appreciated. [1] Simply stated, inherent anticipation exists where although a limitation of a merits is not expressly taught in the prior fine art reference, the claim limitation necessarily and inevitably will be nowadays when the teaching of the prior fine art is practiced. The idea beingness that if the field of study matter already exists in the prior art, then it is not patentable. Interestingly, still, there does not have to be whatever formulation of the invention in the prior fine art for there to be inherent anticipation. Specifically, it is not necessary that anyone previously understood the existence of the inherent discipline matter. [2] The courts often express this by proverb that a newly discovered feature of a known invention is non patentable. In other words, if the feature is always present when practicing the prior art, whether appreciated or not, a patent cannot later on be granted on an invention directed to the feature once it is discovered. Ane example of this can be establish in the In re Cruciferous Sprouts [3] case. In that case the inventors had discovered that eating certain cruciferous sprouts high in glucosinolates had significant health benefits. Information technology was undisputed that the benefits of eating these plants was non previously understood or appreciated. Yet it was also articulate from the tape that the prior fine art taught eating the same sprouts subsequently discovered to be high in glucosinolates. Thus, the court ended that when following the prior art teaching to eat these sprouts, the eater would inherently feel the claimed benefit; thus the claims are inherently anticipated and not patentable.
To inherently conceptualize, the prior art does not need to expressly teach each claim limitation, but it must enable one skilled in the art to practise the claimed invention, including the inherent limitations. The instance law addresses the enablement issue by requiring that the inherent limitation must exist the necessary and inevitable upshot of practicing the teaching of the prior fine art. [4] It is often quite hard to establish that a claim limitation necessarily and inevitably exists in a prior art reference. The limitation must always be nowadays when practicing the fine art. Inherent anticipation cannot be established past mere possibilities. It is not sufficient that sometimes the inherent characteristic results; it must always be in that location.
Discussed herein is how the courts take viewed practiced witness testimony with respect to proving inherent anticipation and what pitfalls parties accept encountered in efforts to utilize experts to plant or refute inherency.
The first result is to make up one's mind whether to use an skilful witness to help establish inherency. The answer should near always be yep. When defenses of inherent anticipation have been successful, the courts have inevitably relied on practiced testimony to resolve whether a claimed characteristic is inherent in the prior art. Indeed, when an argument of inherency has been put forth without the benefit of good testimony, the courts have often establish the evidence to be inadequate. [5] While there may be fact situations that would allow inherency to be established without the benefit of skillful testimony, those circumstances volition likely exist relatively rare.
Adept testimony should be focused on direct establishing that the missing claim element is inherent in the prior art. Specifically, the testimony must constitute by clear and convincing evidence that the claimed characteristic is always present when practicing the teaching of the prior fine art reference. [6] When an expert's analysis is not directed specifically to the claimed limitation, the court may observe that the brunt of establishing inherency has not been carried. [7]
Often the best style to establish inherency is to have your practiced replicate the prior art and test the results to demonstrate the presence of the missing merits element. This tin, even so, be a risky suggestion. Inherency requires that the missing claim element exist nowadays every time the prior fine art education is expert. Therefore, an unsuccessful or poorly run test could damage your ability to brand the inherency statement. All the same, the failure to practice appropriate testing tin also weaken your instance. An practiced may be vulnerable to criticism if he had the power to run tests to support his position but chose not to. An expert must have facts on which to base his opinion; but reciting a political party's contentions in an expert report will more often than not not suffice. [viii] One of the best places to go these facts is from testing. Of class there are potentially other sources, such as published manufactures in the relevant field, simply very piffling is as relevant as replicating the prior art relied upon for anticipation.
Of form replicating the prior art is not always as easy as information technology may seem. Often the prior fine art omits details that the expert must fill in with his experience. For instance, the prior art may teach a process only not specify certain process weather, such as temperature, residence time, reaction equipment, or the like. In such a case, these omissions may require testing of multiple variables to fully found inherency. Very often, choices must be made when attempting to replicate the prior fine art. This requires that the good exist involved in the planning of whatsoever experimentation, and the potential issues should be fully evaluated before the testing begins. If choices are made to limit the testing to a detail variation, then there must be a defensible justification for any choices made in this regard. Failure to be faithful to the prior art in the replication endeavour tin destroy your expert's brownie and render his testimony of no value to the courtroom. [9]
It is also important to make certain the expert'southward testimony is fully supported past the bear witness. [10] If the skillful stretches her testimony (i.e., is perceived as an advocate rather than but as an expert) again it tin destroy her brownie and reduce the chances of establishing inherency through her testimony. In other words, do not allow an practiced to overreach. If the statement requires your expert to overreach, then in that location is an outcome with the argument or the support for it. Those issues should exist addressed well earlier the preparation of the good report. [11]
Just as of import as your skillful testimony is the testimony of the opposing party's expert. More often than not when it comes to basic scientific principles, experts have a hard time disagreeing with each other. Few things are more convincing to the court than testimony of an opposing proficient that supports your position. Therefore it is important to understand the positions that opposing experts are taking, the footing for their positions, and how to claiming those positions at degradation in advance of trial. The courts take considered agreement among the experts convincing with respect to inherency [12] . It tin be very powerful evidence.
The defense of inherent anticipation carries with information technology a high standard of proof to reach the level of clear and convincing evidence. [thirteen] Expert witness testimony is most often disquisitional in determining whether this standard has been met. As tin can be seen from the courts' treatment of expert testimony on this issue, it is of import that the expert'south testimony be well thought out, consistent, and cognizant of the challenges to that testimony. Not every case is appropriate for an inherent anticipation statement. But when the facts support such an statement, properly prepared skillful testimony is ofttimes a key gene in a successful outcome.

[five] See Television set Interactive Information Corp. v. Sony Corp., No. C x-0475 PJH, 2012 WL 6020113 (N.D. Cal. December. 3, 2012). Defendant, Sony, moved for summary judgment arguing inherent anticipation based on a published Japanese patent application. The awarding did not expressly teach ane claim limitation, but Sony argued it was inherent in the UNIX operating organization utilized in the application. Sony manifestly supported its statement with claim charts only no skilful testimony. The Court held that Sony had not carried its burden as the claim charts were non testify and without expert testimony the textile cited by Sony was "incomprehensible to the courtroom." Id. at *22. But see Centricut, LLC v. Esab Group, Inc., 390 F.3d 1361, 1369 (Fed. Cir. 2004) (skilful testimony not required when the technology is easily understood).
[half dozen] Run across Haberman five. Gerber Prods. Co., 236 Fed. Appx. 592 (Fed. Cir. 2007). The Federal Circuit reversed a finding of inherent anticipation on a patent directed to the valve in a sippy cup, noting that no evidence was introduced as to the claimed quantum of pressure necessary to operate the prior art valve. The Federal Circuit concluded that at about the bear witness established that applying some amount of suction "may" result in drawing liquid through the prior art valve. The court establish this evidence insufficient to meet the articulate and convincing standard that the prior fine art necessarily functions in a style inside the scope of the claim. Id.
[seven] In Atofina v. Great Lakes Chemical Corp., 441 F.3d 991 (Fed. Cir. 2006), the Federal Circuit reversed a finding of anticipation based in role on inherency. The claims at issue were directed to a method for making difluoromethane. One of the limitations of the merits required a contact fourth dimension with a catalyst of between 0.01 and 10 seconds. The prior fine art was silent with respect to contact time. The court concluded that Defendants testify was bereft to establish that the contact times were inherent. Specifically the defendants had presented evidence nigh the size of the reaction tube and the menstruum rates through the tubes (presumably in an effort to demonstrate how long the reactants were present in the reaction tube). The court, however, ended that this evidence "do[es] not say annihilation near whatsoever contact times." Id. at k. The court then concluded that the evidence was bereft to institute that the missing limitation must necessarily be present in the didactics of the prior art.

Defendants ran no experiments to back up their position and cited to no scientific papers that supported the position. The but prove that Defendants relied upon was the testimony of an adept, which the court gave no weight, characterizing it every bit "merely a recitation of Defendants' theory" and unsupported past any extrinsic evidence. Id. at *47.

The Plaintiff'south good and the Court read the prior fine art procedure to crave the use of anhydrous ammonia (lacking water). The Defendant's expert had used ammonia that included water in his replication, thus the Court discounted the evidence. Id. at 679.See also Valeant Int'fifty. (Barbados) v. Watson Pharms., Inc., No. ten-20526-CIV, 2011 WL 6792653 (S.D. Fla.)

Fed. Express Corp., No. vi:07-CV-1819-ORL-28KRS, 2010 WL 2639564 (M.D. Fla.) (holding that the inherency argument failed because information technology was "not supported past a single prior art reference and extrinsic evidence explaining inherent features.").
[11] An adept should be given all the relevant information when developing his testimony on inherency. Failure to provide the good with the information could return his testimony of footling value. Run into In re Omeprazole Litigation, 483 F.3d 1364 (Fed. Cir. 2007), where the finding of inherency rested in part upon an admission about the nature of the prior art that plaintiff made during a related Korean litigation. Plaintiff's adept testimony was discounted because he was not provided with the testing done in conjunction with the Korean litigation. Id. at 1372.
[12] See, SRAM Corp. 5. AD-II Eng'g., Inc., 367 Fed. Appx. 150 (Fed. Cir. 2010). The Federal Circuit found in that location was no factual dispute with respect to the presence of the inherent feature (bounty for lost motion) in the prior fine art equally both parties' expert testified as to its presence in the art. Particularly important was the "admission" from Plaintiff'due south expert that the while prior art "may have compensated for cumulative lost motion, they did so in a impuissant and imprecise style."); see also Exergen Corp. 5. Wal-Mart Stores, Inc., 575 F.3d 1312 (Fed. Cir. 2009) (finding that Plaintiff's experts' testimony supported a finding of inherent apprehension).
