In re Gianelli, Fed. Cir. No. 2013-1167 (1/13/2014)‎

In this appeal from the PTAB, the Federal Circuit reversed a determination of obviousness based ‎on the ‎panel's holding that "adapted to" is not synonymous with "capable of" when considering ‎whether one of ordinary skill would have thought to modify a prior art exercise machine to ‎arrive ‎at the claimed invention. Because these terms are commonly used claim terms, the court's ‎holding is ‎one to closely consider.‎

The claim at issue ‎recites:‎

A row exercise machine comprising an input assembly including ‎a first handle ‎portion ‎adapted to be moved from a first position to ‎a second position by a pulling force exerted by a ‎user on ‎the first ‎handle portion in a rowing motion, the input assembly defining a ‎substantially linear ‎path for ‎the first handle portion from the first ‎position to the second position.‎ (emphasis added)

The claims were rejected under sections 102 and 103 based a '447 patent, which describes a ‎chest ‎press exercise machine in which the user ‎performs the exercise by pushing on the handles. ‎The PTAB affirmed the rejection, characterizing the dispositive ‎issue as ‎whether the chest press machine of the '447 ‎patent was "capable of being used by exerting a ‎pulling ‎force on the handles in a rowing motion."‎

The panel noted that the phrase "adapted to"' is frequently used to mean "made to," "designed ‎to," ‎or "‎configured to." Aspex Eyewear, Inc. v. Marchon Eyewear, Inc., 672 F.3d 1335, 1349 ‎‎(Fed. ‎Cir. ‎‎2012). Although the phrase can also mean "capable of" or "suitable for," here ‎the ‎written ‎description makes clear that "adapted to," as used in the subject application, has a ‎narrower ‎meaning, ‎viz., that the claimed machine is designed or constructed to be used as a ‎rowing ‎machine whereby a ‎pulling force is exerted on the handles.‎ "Consequently, the relevant ‎question before the Board was ‎whether the apparatus described in the ‎‎'447 patent was "‘made to,' ‎‎‘designed to,' or ‘configured to,'" ‎allow the user to perform a ‎rowing exercise by pulling on the ‎handles as claimed in the '261 ‎application.‎"‎

There was no question that the '447 patent does not ‎have ‎handles that are adapted to be pulled in a ‎rowing motion. The Board stated that using the '447 ‎patent ‎as a ‎rowing machine was a new intended use of the prior art apparatus. In the ‎context of the ‎claimed ‎rowing machine, however, the panel ruled that the mere capability of pulling the handles is not ‎the inquiry the ‎Board ‎should have made. Instead; it should have determined whether it would have ‎been obvious to modify ‎the ‎prior art to arrive at the claimed rowing machine. The panel felt it was not obvious to modify a machine ‎with ‎handles designed to be pushed to one with ‎handles adapted to be pulled. A chest press machine ‎is not ‎a rowing machine, nor has evidence ‎been shown that it is. ‎

Because the Board's analysis began with the premise that "adapted to" meant "capable ‎of," ‎its ‎affirmance of the rejection contained no explanation why or how a ‎person ‎having ‎ordinary skill in the art would modify the prior art chest press machine to arrive at the ‎claimed ‎apparatus. Because the initial burden was not met, under In re ‎Rijckaert, 9 ‎F.3d ‎‎1531, 1532 (Fed. Cir. 1993), ‎Giannelli was not obligated ‎to ‎submit ‎additional evidence to rebut the examiner's findings of pulling capability. The Board thus ‎erred in ‎affirming the conclusion of the examiner that the '447 ‎patent apparatus rendered obvious the ‎claimed ‎invention of the '261 application.‎

This case shows that care should be taken in using "adapted to" in drafting a claim unless a narrow definition is intended, and may prove helpful to those arguing at the Markman stage that "adapted to" must be narrowly construed. ‎If a broader construction is intended, clear support for that construction must be included in the specification.

Proveris Scientific Corporation v Innovasystems, Inc., Fed. Cir. No. 2013-1166 (1/13/2014)‎

Innovasystems ("Innova") appealed a judgment holding it in contempt of an injuction and awarding ‎‎$878,205 in sanctions. The Circuit vacated the contempt order and remanded the case because ‎the district court had not construed the claim language at issue. In so ruling, the panel discussed a ‎number of issues of interest: the tests to be applied in deciding whether a contempt order is ‎appropriate; when claim construction requires language in the preamble to be considered limiting; ‎whether a defendant that did not previously challenge validity is permitted to do so at the contempt stage; and whether overseas sales of component parts of a device found to directly ‎infringe and is the subject of an injunction should be the basis of a finding of contempt.‎

Proveris sued Innova for infringement of a patent directed to an apparatus for evaluating the delivery ‎of drugs via aerosol spray. Innova conceded infringement of independent claim 3, among other claims, ‎by its Optical Spray Analyzer ("OSA"). The district court ‎ruled in favor on Proveris on validity, and granted Proveris a permanent injunction prohibiting Innova ‎from selling the OSA, and from importing it into or exporting it out of the U.S. The Circuit affirmed this ‎order in 2008. ‎

Innova subsequently modified its product, which it now called the Aerosol Drug Spray Analyzer ‎‎("ADSA"). Innova claimed the OSA product had allowed a user to identify what range of images he or ‎she ‎wanted to analyze before activating the spray plume, while the ADSA device requires the user ‎to ‎first activate the spray plume and then determine what range of images he or she would ‎like ‎to analyze. Innova contended this was a significant modification that renders the ADSA device non-‎‎infringing because the preamble of claim 3 specifies that the image data may be captured "at ‎a ‎predetermined instant in time."‎

Proveris disagreed and filed a ‎motion for contempt. The district ‎court ‎ruled that, because Innova could ‎have raised claim construction issues in the earlier ‎infringement action, the court would not construe ‎claim 3 or import ‎the "at a ‎predetermined instant in time" limitation from the ‎preamble of claim 3. The ‎district court also said that, because Innova had unsuccessfully challenged the validity of claim 3 ‎during the infringement action, it could not raise ‎new invalidity arguments in the contempt ‎proceeding. The district court thus ‎entered a contempt order, implicitly finding that the ADSA product ‎was ‎not more than colorably different from the infringing OSA product and that it, too, infringed the ‎patent.‎ The court found that Innova's ‎violation of the injunction had been willful and ordered ‎disgorgement of any profits Innova ‎made from sales of the ADSA product. Proveris also sought to recover ‎profits from Innova's ‎sale of component parts to overseas customers, but the district court ruled that ‎those ‎actions did not fall within the scope of the original injunction and therefore refused to include ‎those sales in its contempt order or in the award of profits.‎‎

In evaluating whether the contempt order was appropriate, the panel cited the two-step test outlined ‎in TiVo Inc. v. Echostar Corp., ‎‎646 F.3d 869 (Fed. Cir. 2011) (en banc). First, a party seeking to enforce ‎an injunction must ‎show that "the newly accused product is not more than colorably different from ‎the product ‎found to infringe." The analysis should focus on "those aspects of the accused ‎product ‎that were previously alleged to be, and were a basis for, the prior finding of infringement, ‎and ‎the modified features of the newly accused product." Where one or more of the ‎elements ‎previously found to infringe has been modified or removed, the court must determine ‎whether ‎that modification is significant. If so, the newly accused product is more than ‎colorably ‎different from the infringing product, a contempt ruling is not appropriate, and a ‎new ‎infringement action must be brought. If, however, the differences are not more than colorable, the ‎court must then go on to a ‎second step and determine whether the newly accused product in fact ‎infringes the ‎claims.‎

Colorable Difference

Innova argued that the OSA product was admitted to infringe claim 3 in part because that device ‎had ‎the ability to specify which images should be captured "at a predetermined time," meaning ‎before the ‎spray plume was activated. Thus, following the TiVo analysis, Innova argued that the ‎ADSA product was ‎more than colorably different from the OSA. The panel disagreed with Innova's reading of TiVo, ‎as TiVo ‎makes clear that the court must still determine whether that modification was significant. The ‎panel found that the modification was not significant because the User Manuals for both the OSA and ‎the ADSA products instruct the user to select the range of images to be analyzed after the actual spray ‎event ‎takes place. Given this, the panel agreed with the district court that the two ‎products are ‎functionally identical and therefore not more than colorably different.‎


The panel then turned to the issue of whether the ADSA product infringes the original patent, which ‎requires construction of the disputed claim terms. Here, the ‎district court declined to construe the ‎disputed claim language because it felt that any arguments about the ‎construction of claim 3 should ‎have been raised in the earlier infringement action. The panel agreed that in contempt proceedings, ‎‎"out of fairness, the ‎district court is bound by any prior claim construction that it had performed in the ‎case." However, here, there was no prior claim construction because Innova had ‎conceded ‎infringement. Thus, it simply cannot be said that it was the "law of the case" that the ‎preamble was ‎not a claim limitation. ‎

The panel then determined for itself whether the preamble should be imported as a ‎limitation in the claim. ‎

Claim 3 reads:‎

‎An apparatus for producing image data representative of at least ‎one sequential set of images of a ‎spray plume, each of the images ‎being representative of a density characteristic of the spray plume ‎‎(i) ‎along a geometric plane that intersects the spray plume, and (ii) ‎at a predetermined instant in time, ‎comprising:‎

an illuminator for providing an illumination of the spray plume ‎along at least one geometric plane that ‎intersects the spray plume; ‎and,‎

an imaging device for generating the image data representative of ‎an interaction between the ‎illumination and the spray plume along ‎the at least one geometric plane.‎

‎The panel looked to NTP, Inc. v. Research In ‎Motion, Ltd., 418 F.3d 1282, 1305 (Fed. Cir. 2005), which ‎stated: "A preamble is generally construed to be limiting if it recites essential structure or steps, ‎or if it ‎is necessary to give life, meaning, and vitality to the claim." Additionally, "[w]hen limitations in the ‎body ‎of the claim rely upon and derive antecedent basis from the preamble, then the preamble ‎may act as a ‎necessary component of the claimed invention." ‎

Both of those considerations support the conclusion that the preamble is limiting in this ‎case. First, the ‎specification identifies the invention as producing a "sequential set of images" and ‎focuses on the ‎ability of the invention to capture "the time evolution of the spray."‎ The preamble of claim 3 is the only ‎reference ‎in any independent claim to the inventive concept of capturing a sequence of images in ‎order to ‎characterize the time evolution of the spray plume. The claim body also supports importing the preamble as limiting because the phrase ‎‎"the image data" in the body of the claim derives antecedent basis from ‎the "image data" that is defined in greater ‎detail in the preamble." The panel thuse held that the preamble here should ‎be ‎construed as importing a limitation into the claim.‎

The panel determined that it did not have enough information to resolve other claim construction issues in the claim‎. Although claim ‎construction is a question of law, where a district court ‎has offered no reasoning to review, ‎the panel noted it may decline to construe the claims in the first ‎instance. Thus, the case was remanded to the district court to determine the proper construction ‎of ‎the disputed claim language, and then decide whether the ADSA product infringes claim 3 ‎and ‎therefore constitutes a violation of the injunction.‎


The panel also instructed the district court that regardless of what claim construction the court ‎adopts on ‎remand, Innova is not entitled to present new invalidity arguments at the contempt stage. ‎In contrast to ‎claim construction, validity was disputed in the underlying infringement lawsuit, so ‎Innova has ‎already had a full and fair opportunity to present its arguments relating to the invalidity of ‎claim ‎‎3.‎


The panel noted that it saw no error in the court's denial of sanctions for Innova's ‎overseas sales of ‎component parts, since liability for those sales is premised on 35 U.S.C. § ‎‎271(f), while the underlying ‎infringement action alleged direct infringement by sales of ‎whole products. Because of this ‎substantive difference, the panel held that the court did not err in concluding that a contempt ruling ‎was not appropriate as to those sales.‎
