Before SMITH, NIES and ARCHER, Circuit Judges.
This is an appeal from the decision of the United States Patent and Trademark Office, Board of Patent Appeals and Interferences (Board), awarding priority of invention to the senior party, Catherine Plet (Plet), on the ground that the junior party, Robert S. Lutzker (Lutzker), had suppressed or concealed the invention within the meaning of 35 U.S.C. Sec. 102(g) (1982) and on the ground that Lutzker failed to comply with the duty of disclosure required by 37 C.F.R. Sec. 1.56(a). We affirm on the basis of the suppression and concealment and do not consider the failure to comply with section 1.56(a).
The invention at issue is a device for making canapes. Lutzker introduced into evidence before the Board a drawing showing every element of the invention of the count in issue. The drawing is dated February 1, 1976 and is signed by Lutzker and witnessed by his wife, his step daughter, and two friends. The Board found that Lutzker established conception of the invention as of February 1, 1976 on the basis of this disclosure. The Board further found that Lutzker established an actual reduction to practice of his invention by the end of March 1976. A commercially acceptable version of his invention was disclosed to the public at a July 14, 1980 Housewares Show. Lutzker filed a patent application on November 24, 1980.
Plet's invention was constructively reduced to practice on the effective filing date of her patent application (March 3, 1980), i.e., the filing date of Plet's parent application. The Board found that Plet "established a date of conception no later than August 17, 1979."
With respect to Lutzker's delay in making his invention publicly known, the Board stated that
[t]he period from ... [Lutzker's] reduction to practice in March 1976 to the date of the show is over 51 months and is clearly such an unreasonable length of time that it raises an inference of suppression on the part of Lutzker.... Thus, the burden falls on Lutzker to excuse, explain or justify the delay.
The Board determined that Lutzker's activities during this period were insufficient to overcome the inference of suppression of the invention because they were "directed primarily toward commercializing the invention." Moreover, the board found that Lutzker's actions "involve a deliberate policy on his part not to disclose his invention to the public until he is ready to go into commercial production."
The Board recognized that "Lutzker could still prevail on the question of priority if he could show ... [renewed activity] during the critical period from just prior to Plet's entry into the field until Lutzker's November 24, 1980 filing date." The Board found, however, that "the renewed activities relied upon by Lutzker did not start until after Plet entered the field" and therefore that "Lutzker is not entitled to prevail on the basis thereof."
OPINIONGenerally, the party who establishes that he is the first to conceive and the first to reduce an invention to practice is entitled to a patent thereon. However, the second party to conceive and reduce the same invention to practice will be awarded priority of invention if he can show that the first party to reduce to practice abandoned, suppressed or concealed the invention. 35 U.S.C. Sec. 102(g); Paulik v. Rizkalla, 760 F.2d 1270, 226 USPQ 224 (Fed.Cir.1985).
The Board found that Lutzker was the first to conceive and first to reduce the invention to practice, but that he suppressed or concealed his invention after his reduction to practice. There are two ways in which Lutzker can be awarded priority with respect to the count at issue: (1) by showing that the Board erred in finding that he suppressed or concealed his invention; or (2) by showing that the board erred in finding that he had not resumed work on the invention which was the subject of his patent application from a time prior to Plet's entry into the field. See Brokaw v. Vogel, 429 F.2d 476, 480, 166 USPQ 428, 431 (CCPA 1970) ().
In Correge v. Murphy, 705 F.2d 1326, 1330, 217 USPQ 753, 756 (Fed.Cir.1983) (quoting International Glass Co. v. United States, 408 F.2d 395, 403, 159 USPQ 434, 441 (Ct.Cl.1968)), the court held:
The courts have consistently held that an invention, though completed, is deemed abandoned, suppressed, or concealed if, within a reasonable time after completion, no steps are taken to make the invention publicly known. Thus, failure to file a patent application; to describe the invention in a publicly disseminated document; or to use the invention publicly, have been held to constitute abandonment, suppression or concealment.
Moreover, when there is an unreasonable delay between the actual reduction to practice and the filing of a patent application, there is a basis for inferring abandonment, suppression or concealment. Horwath v. Lee, 564 F.2d 948, 951-52, 195 USPQ 701, 705 (CCPA 1977). The inventor's activities during the delay period may excuse the delay (e.g., he may have worked during that period to improve or perfect the invention disclosed in the patent application). Id. at 952, 195 USPQ at 705; Young v. Dworkin, 489 F.2d 1277, 1281 n. 3, 180 USPQ 388, 391-92 n. 3. (CCPA 1974); Frey v. Wagner, 87 F.2d 212, 215, 32 USPQ 239, 242 (CCPA 1937) ()
Lutzker reduced his invention to practice by the end of March 1976, but his first public disclosure was in July 1980. The Board correctly found this delay of approximately fifty-one months was unreasonably long and sufficient to give rise to an inference of an intent to abandon, suppress, or conceal the invention. See, e.g., Paulik v. Rizkalla, 760 F.2d at 1273-75, 226 USPQ at 226-27 ( ); Peeler v. Miller, 535 F.2d 647, 653-54, 190 USPQ 117, 122-23 (CCPA 1976) ( ); Shindelar v. Holdeman, 628 F.2d 1337, 1342-43, 207 USPQ 112, 117 (CCPA 1980), cert. denied, 451 U.S. 984, 101 S.Ct. 2317, 68 L.Ed.2d 841 (1981) ( ).
An inference of suppression or concealment may be overcome with evidence that the reason for the delay...
