Opinion

DYK, Circuit Judge.

Clock Spring, L.P. (“Clock Spring”) brought suit alleging that Wrapmaster, Inc. (“Wrapmaster”) infringed the claims of U.S. Patent No. 5,632,307 (“'307 Patent”) and violated section 43(a) of the Lan-ham Act, 15 U.S.C. § 1125(a)(1)(A). The '307 Patent claims methods for repairing damaged high-pressure gas pipes. On summary judgment the United States District Court for the Southern District of Texas held that the claims of the '307 Patent were invalid due to obviousness and that the Lanham Act claim was without merit. We affirm the summary judgment of invalidity because we conclude that the claims of the '307 Patent are invalid as a matter of law, due to prior public use. We do not reach the issue of invalidity due to obviousness. Additionally, we affirm the district court’s summary judgment determination that the false advertising claim is without merit.

BACKGROUND

Both Clock Spring and Wrapmaster are high-pressure gas pipeline repair companies. Clock Spring is the exclusive licensee of the '307 Patent. The '307 Patent has five independent claims and thirty-eight dependent claims. All are method claims. Claim 1 of the '307 Patent reads as follows:

A method for repairing a pipe adapted to carry an internal load directed radially outward therefrom, said pipe having a defective region defined by at least one cavity extending from an outer surface of said pipe toward the center of said pipe but not extending completely through the wall of said pipe, said method comprising the steps of:
providing a filler material having a workable uncured state and a rigid cured state,
filling said cavity to at least said outer surface of said pipe with said filler material in said workable state, providing at least one band having a plurality of elastic convolutions of high tensile strength material, while said filler material is in said workable state, wrapping said plurality of convolutions of said high tensile strength material about said pipe to form a coil overlying stud filler material[,]
tightening said coil about said pipe so that said filler material completely fills that portion of said cavity under *1322 lying said coil[,] securing at least one of said convolutions to an adjacent one of said convolutions, and
permitting said filler material to cure to said rigid state, whereby a load carried by said pipe is transferred substantially instantaneously from said pipe to said coil.

'307 Patent col.12 11.9-34 (emphases added). The parties appeared to agree, or at least not contest, that the main distinctive feature over the prior art is wrapping the pipe while the filler is in an uncured state so as to ensure smooth and continuous contact between the wrap and the pipe. The other independent claims (claims 38, 39, 42, and 43) also require wrapping in an uncured state, but address different types of defects and repair methods. The various dependent claims add further limitations for the properties of the materials used in the individual steps of the method (e.g., requiring that the filler’s “rigid cured state has a compressive strength of at least about 9,000 psi”). '307 Patent col.12 11.59-60.

In 2005 Clock Spring filed an infringement suit against Wrapmaster alleging infringement of all the claims of the '307 Patent. It also filed a separate Lanham Act suit alleging that Wrapmaster “used in commerce a false and misleading description of fact, and false and misleading representation of fact, which in commercial advertising or promotion, misrepresents the nature, characteristics and qualities of [Clock Spring’s] goods, services, and commercial activities.” Pl.-Appellant’s Compl. at 30, Clock Spring, L.P. v. Wrapmaster, Inc., No. 4:05-CV-01388, 2005 WL 1244210 (S.D.Tex. April 20, 2005). The two suits were consolidated.

After discovery, Wrapmaster filed a summary judgment motion of invalidity of all the claims of the '307 Patent and a separate summary judgment motion on the Lanham Act claim. Somewhat surprisingly, neither motion was supported by expert affidavits. We treat the two motions separately.

The invalidity summary judgment motion argued that the claims were invalid due to a prior public use under 35 U.S.C. § 102(b) in October 1989, in Cuero, Texas, more than one year before the patent application was filed in 1992. The motion was supported by a 1994 Gas Research Institute (“GRI”) report (hereinafter “1994 GRI report”) regarding the demonstration made by named inventor Norman C. Faw-ley (“Fawley”). 1 GRI, since renamed the Gas Technology Institute, is a non-profit research and development organization which was entitled to receive royalty payments from Clock Spring on the '307 Patent. The motion also urged that the claims were invalid on grounds of obviousness based on a number of prior art patents. 2

Clock Spring opposed the motion. Clock Spring did not dispute that the 1989 demonstration was public, or that it involved the limitations of the patent with one exception. Clock Spring apparently urged that the 1989 demonstration had not involved the application of the wrap with an uncured filler, and that the use had been experimental. Clock Spring also urged that the patent claims were not obvious.

The district court referred the motion to a magistrate judge for recommendations. The magistrate judge recommended that *1323 the district court grant summary judgment of invalidity with respect to the claims of the '307 Patent.

The magistrate judge first addressed Wrapmaster’s contention that the '307 Patent is invalid due to prior public use. The magistrate judge concluded that the 1994 GRI report proved that there was no genuine issue of material fact regarding whether the filler compound was uncured when the wrap was applied to the pipe. The magistrate judge also rejected Clock Spring’s argument that the use was experimental. Based on this, the magistrate judge recommended finding that the 1989 demonstration triggered the public use bar under 35 U.S.C. § 102(b). Clock Spring, L.P. v. Wrapmaster, Inc., No. 4:05-CV-00082, slip op. at 11-12 (S.D.Tex. Dec. 19, 2007).

The magistrate judge then addressed Wrapmaster’s contention that the claims of the '307 Patent are invalid due to obviousness. In her analysis, the magistrate judge primarily relied upon the combination of the '524 Patent with the '337 Patent. The '524 Patent’s claims closely follow most of the claims for methods of repairing a pipe from the '307 Patent with the notable exception of any limitation requiring wrapping the pipe while the filler material is still in its uncured state.
