D. The'105 Patent
The '105 patent is titled "Double Cylinder Assembly for Raising and Lowering a Dump Truck Tailgate." Ex. 1001, [54]. The '105 patent issued from Application Serial No. 12/171, 321, filed on July 11, 2008, and claims priority to Provisional application No. 60/959, 394, filed on July 13, 2007. Id. at [21], [22], [60].
The '105 patent relates to "mechanisms for raising and lowering a tailgate provided on a dump box of a dump truck, trailer, or similar vehicle," specifically "a double cylinder assembly for raising and lowering such a tailgate that is pivotably supported on the dump box." Id. at 1:13-17.
The '105 patent describes a "typical dump truck" where "the open rear end of the dump box includes a pair of upstanding corner posts that are each formed from a hollow rectangular member" and which support a pivoting tailgate. Id. at 1:18-31. The tailgate is often moved between open and closed positions "by means of a cylinder (typically a pneumatic cylinder) that extends between the dump box and the tailgate." Id. at 1:32- 35. The patent explains that the cylinder is typically located either in the hollow corner post, vertically, even though the corner post size may be "limiting," or horizontally, on the outside of the dump box walls, which is inexpensive to install, but "does undesirably expand the overall width of the vehicle." Id. at 1:42-58. To address these issues, the patent describes an improvement using a "double cylinder assembly." Id. at 2:9-11.
Figure 4, reproduced below, shows a perspective view of a dump truck with a double cylinder assembly on each side of a tailgate.
(Image Omitted)
Id. at Fig. 4. Figure 4 shows a dump truck 30 from a rear, perspective view, and having a raised dump box 31, corner posts 36, raised tailgate 37, and double cylinder assembly 40. Id. at 3:28-48. The '105 patent describes that:
two double cylinder assemblies 40 fit more efficiently within the respective hollow rectangular shape of the corner posts 36 than a conventional single pneumatic cylinder having a square or circular cross sectional shape. Therefore, the two double cylinder assemblies 40 provide more force than the single pneumatic cylinder could provide for a given size of the corner posts 36.
Mat 4:12-18.
Of the challenged claims, claims 1 and 11 are independent. Id. at 4:44-63, 5:30-6:10. Claims 2-10 depend directly or indirectly from claim I. Id. at 4:64-5:29. Claims 12-20 depend directly or indirectly from claim II. Id. at 6:11-43.
Petitioner proposes that a person of ordinary skill in the art "would have had at least several years of practical academic or industrial experience designing, testing, manufacturing, selling and/or servicing dump trucks and/or dump bodies with, or supported by a person with, a bachelor of science in a field of engineering or a closely related discipline." Pet. 10 (citing Ex. 1012 ¶ 27).
Patent Owner proposes that a person of ordinary skill "would be as follows: A mechanical engineer having at least five year's industrial experience in the engineering and design of dump bodies with high lift tailgates, including cylinder assemblies, for dump trucks." Prelim. Resp. 4 (citing Ex. 2001 ¶ 34). Patent Owner argues that in setting forth its proposed level of ordinary skill, "Petitioner has cast a very wide net, covering a person with at least several years' experience in sales of dump bodies to one with 30 years' experience in testing, designing, manufacturing, servicing, and selling dump trucks and dump bodies." Id. at 6.
In our Decision on Institution, we agreed with Patent Owner that Petitioner's proposal is relatively broad given the repeated use of "and/or" in the definition and the vagueness of the term "several years." Dec. 7. We concluded that "[f]or purposes of this Decision, we adopt Patent Owner's proposed level of ordinary skill, as it appears to be consistent with the level of skill, and choice of language, reflected by the specification and in the asserted prior art references." Id.
At the oral hearing, we asked Patent Owner a number of questions about its definition. Tr. 15:15-17:12, 24:4-27:26. With this fully developed record, we reconsider the definition of a person of ordinary skill. The factors influencing the proper definition of a person of ordinary skill include: "(1) the 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 active workers in the field." Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007).
With a complete record, we discern several problems with Patent Owner's definition. The first problem with Patent Owner's definition is the inclusion of the term "high-lift tailgates," which is not found in the '105 patent. See Tr. 14:21-16:3 ( ). We decline to require such narrow expertise in a subject not discussed in the challenged patent. The prior art of record suggests that a person of ordinary skill would have experience with a wide variety of types of dump trucks and dump bodies. See, e.g., Ex....
