The Board found claims 1–13, 27, and 30–32 not shown unpatentable because the proposed obviousness combinations did not establish the claimed mechanical lockdown mechanism and its required function.
RulingsFinal written decision- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner
“The parties do not dispute that a “lockdown mechanism” maintains the mandrel in a fixed position during a fracking or well treatment operation. Thus, we will construe “lockdown mechanism” to mean “machinery for maintaining [the mandrel] in a fixed position during a fracking or well treatment operation.” This leaves us to determine what it means for a lockdown mechanism to be “mechanical” and whether the correct construction requires imposing a further definitional limitation regarding a range of adjustment. Oil States points out that the Specification differentiates a mechanical mechanism from hydraulic mechanisms. PO Resp. 12. The Specification distinguishes the instant invention from an earlier invention by the same inventor that discloses a hydraulic unit. Ex. 1001, 2:28–63. The Specification further states that: a mechanical lockdown mechanism for securing the BOP protector mandrel in an operative position is considered more reliable because a source of pressurized hydraulic fluid is not required. Id. at 2:3–6; see also id. at 3:53–56. Greene does not challenge that this language in the Specification effectively differentiates a mechanical lockdown mechanism from a hydraulic mechanism. Thus, we construe “mechanical” lockdown mechanisms as being limited to purely mechanical means such as nuts and bolts and the like. We further clarify that the principal holding force that maintains the mandrel in a fixed position is not a dynamic force such as through hydraulic, pneumatic, or electrical means or the like.” slip op. at 8

“Oil States’s effort to read a “broad range of adjustment” limitation into the definition of mechanical lockdown mechanism in claim 1 renders the dependent limitation in claim 3 superfluous. Claim 2 claims an elongated spiral thread. There is no need to add a further limitation to claim 3 to provide for adjustment to compensate for variations in the distance between a top of the blowout preventer and the top of the casing of different wellheads if a “broad range of adjustment” is already contemplated in the meaning of mechanical lockdown mechanism. 8 It is well-settled that each claim does not necessarily cover every feature disclosed in the specification. See Ventana Med. Sys., Inc. v. Biogenex Labs, Inc., 473 F.3d 1173, 1181 (Fed. Cir. 2006). When a claim addresses only some of the features disclosed in the specification, it is improper to limit the claim to other unclaimed features. Id. Here, Oil States’s inclusion of adjustment limitations in claims 2 and 3 belie an intention to limit the scope of the term “mechanical lockdown mechanism” in claim 1 to mechanisms that provide a broad range of adjustment.9 Thus, we decline to adopt Oil States’s proposed construction. We construe a “lockdown mechanism” to mean “machinery for maintaining [the mandrel] in a fixed position.” In the context of lockdown mechanisms, we construe the adjective “mechanical” to mean that the lockdown mechanism is limited to purely mechanical means such as nuts and bolts and the like so that the principal holding force that maintains the mandrel in a fixed position 8 In the Summary of the Invention section of the Specification, the topic sentence of the paragraph describing an embodiment with a “significant range of adjustment,” qualifies the description of such embodiment with the word “preferably.” Ex. 1001, 3:8–27. This suggests that this passage of the Specification merely describes one embodiment and not the entire invention. 9 To the extent that claim 1 requires the mechanical lockdown mechanism to have any range of adjustment, such adjustment requirement may be found in the claim limitation directed to the lockdown mechanism being “adapted to ensure that the annular sealing body is securely seated against the top of the casing when the mandrel is in the operative position” and not in definition of “mechanical lockdown mechanism” per se.” slip op. at 11

“Green’s expert, Mr. Shackelford, opines that the person of ordinary skill in the art at the time of the invention of the ’993 patent would have had a Bachelor-level degree in a recognized engineering discipline and practical job exposure of several years with oil and gas well operations. Ex. 1002 ¶ 13. Mr. Shackelford’s testimony is entirely conclusory with no supporting factual analysis. Oil States contends that the level of ordinary skill in the art is “relatively low,” but does not articulate or explain what it means by this characterization. PO Resp. 22. Oil States’s expert, Dr. Wooley, merely adopts Mr. Shackelford’s position and, like Mr. Shackelford, fails to provide any supporting factual analysis. Merely reciting a college degree and a number of years of experience provides little guidance as to the actual capabilities of a person of ordinary skill in the art. Neither party presents a detailed evidentiary showing under the factors recited in Environmental Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696–97 (Fed. Cir. 1983). 13” slip op. at 22

“combine references is a question of fact. In re Constr. Equip. Co., 665 F.3d 1254, 1255 (Fed. Cir. 2011). Greene fails to persuade us that a person of ordinary skill in the art would have had reason to combine Herricks and McLeod to achieve the invention claimed in claims 1 and 27 of the ’993 patent. Because the mechanical lockdown mechanism in McLeod is intended to be used with a mandrel that packs off at an indeterminate point in the casing, rather than at a fixed point and, therefore, does not disclose any range of adjustment to accommodate production trees of varying heights as would be necessary to be operable in systems designed for fixed point packoff, the proposed combination does not provide a mechanical lockdown mechanism that is adapted to securely seat a mandrel against the top of the casing as required by claim 1. Similarly, the proposed combination does not provide a method for engaging the mechanical lockdown mechanisms to lock the mandrel in the operative position such that the annular sealing body is in fluid sealing engagement with a top of a casing of the well as required by claim 27.” slip op. at 30

“Notwithstanding the scant evidence on skill level presented by the parties, the level of skill in the art can often be determined from a review of the prior art. See Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163–64 (Fed. Cir. 1985). Based on our review of the prior art and the other technology related exhibits of record that are contemporaneous with the date of the invention, the applicable art is hard disk drive assembly and similar precision machinery. The person of ordinary skill in this field would have been familiar with hard disk drive design and assembly in general and the use of tolerance rings in conjunction with actuator bearing cartridges in particular. Ex. 2001; Ex. 2016. The ordinarily skilled artisan would have been familiar with both Shaft Variable and Housing Variable tolerance rings and their manner of assembly with a bearing shaft and a bore. Ex. 1001, Admitted Prior Art. Such an artisan also would have been familiar with the problem of debris or particle generation during assembly of a hard disk drive. Ex. 2003; Ex. 1001, 2:5–17. Such a person would have 17 Factors pertinent to a determination of the level of ordinary skill in the art include: (1) educational level of the inventor; (2) type of problems encountered in the art: (3) prior art solutions to those problems; (4) rapidity with which innovations are made; (5) sophistication of the technology, and (6) educational level of workers active in the field. Not all such factors may be present in every case, and one or more of these or other factors may predominate in a particular case. Id.

“A patentee demonstrates commercial success by showing significant sales of the patented product in a relevant market. J.T. Eaton & Co. v. Atlantic Paste & Glue Co., 106 F.3d 1563 (Fed. Cir. 1997). However, evidence of commercial success is only significant if there is a nexus between the claimed invention and the commercial success. Ormco Corp. v. Align Technology, Inc., 463 F.3d 1299, 1311–12 (Fed. Cir. 2006). In the instant case, Saint-Gobain produced evidence that adding a flared guide portion to a tolerance ring quickly caused sales of flared tolerance rings to supplant sales of non-flared tolerance rings. Saint-Gobain also produced evidence that adding a flared guide portion caused sales of tolerance rings to supplant the sales of other, competing technologies. This evidence indicates that market demand for the flared tolerance ring is attributable to the flared guide portion. We are not persuaded by Intri-Plex’s evidence and argument that the market dominance of flared tolerance rings is attributable to Saint-Gobain coercing customers into sole source agreements. During the period from 2003 to 2007, Saint-Gobain sold tolerance rings with and without a guide portion. We are persuaded that the rapid increase in sales of flared tolerance rings vis-à-vis non-flared rings is more logically explained by customer preference than supplier coercion. Indeed, given the relatively easily discernable difference between the non-flared tolerance rings and the flared tolerance rings, we are hard pressed to come to a determination that the increase in sales of the flared tolerance rings is attributable to anything other than the flared guide portion. In any event, Intri-Plex’s arguments are belied by its own admissions. In response to Saint-Gobain’s allegations of copying, Intri-Plex volunteered that the only reason Intri-Plex made tolerance rings with a flared guide portion is due to customer requests. Pet. Reply 4; Paper 67, 12. Intri-Plex further admitted that the reason that its customers requested flared tolerance rings is because they had set up their manufacturing operations to accommodate a flared tolerance ring to the exclusion of a non-flared ring. Tr. 31:416.19 These admissions constitute strong evidence that the commercial success is attributable to customer demand for the patented features. In summary, the commercial success of flared tolerance rings, whether made and sold by Saint-Gobain or Intri-Plex, weighs heavily in favor of non-obviousness of the invention. 2.

“A party may prove copying by showing that an accused copier had access to the patented product combined with substantial similarity to the patented product. Wyers v. Master Lock Co., 616 F.3d 1231, 1246 (Fed. Cir. 2010). Here, Intri-Plex denies direct copying of Saint-Gobain’s product and asserts, instead, that its alleged copy was made in response to customer requests. However, Intri-Plex does not deny that its customers had access to Saint-Gobain’s product.21 To the contrary, Ryan Schmidt admitted that all of the flared tolerance rings that Intri-Plex made and sold were the result of customers asking Intri-Plex to be a “second source” to Saint-Gobain. Ex. 1033 ¶¶ 20–23, 29; Ex. 1034. We are not persuaded that Intri-Plex can insulate itself from an accusation of copying, merely by interposing an intermediary between itself and Saint-Gobain’s patented product.22 We determine that Intri-Plex’s customers gave Intri-Plex detailed product specifications of a flared tolerance ring because they wanted a second source for Saint-Gobain’s patented product. Whether information concerning Saint-Gobain’s patented product was passed from Intri-Plex’s customers to Intri-Plex in the form of detailed product specifications instead of an actual product sample does not, in our view, negate a finding that Intri-Plex had the 21 Tr. 71:13-15. 22 In the copyright context, courts have found access when the alleged infringer and an intermediary occupy positions such that it is natural that information possessed by one would be imparted to the other. See, e.g., Meta-Film Associates, Inc. v. MCA, Inc., 586 F. Supp. 1346, 1356 (C.D. Cal. 1984); Bevan v. Columbia Broadcasting System, Inc., 329 F. Supp. 601, 610 (S.D.N.Y. 1971). requisite access to Saint-Gobain’s patented product.23 Ex. 1033 ¶ 21; Ex. 1034. On the basis of the facts that (1) Intri-Plex admits that its own commercial product included a flared guide portion and (2) that the flared guide portion was added in response to customer requests for a second source to Saint-Gobain’s product, we are persuaded that Saint-Gobain has shown that Intri-Plex had access to the patented product and that there is substantial similarity between the parties’ respective products, specifically, that both products included flared guide portions. Intri-Plex’s evidence fails to persuade us that this similarity between the parties’ respective products is either a coincidence or the result of independent creation. Consequently, Saint-Gobain’s evidence of copying weighs in favor of a finding that the patented invention is non-obvious.” slip op. at 40
