Foreign Country Patents Not Determinative for Rejection
Note:
A foreign country's designation of a document as a patent is not determinative for rejection under AIA 35 U.S.C. 102(a) or pre-AIA 35 U.S.C. 102(a), (b), and (d); instead, the substance of the rights conferred and control over information within the 'patent' are key.

What a foreign country designates to be a patent may not be a patent for purposes of rejection under 35 U.S.C. 102(a) or pre-AIA 35 U.S.C. 102(a) and (b); it is the substance of the rights conferred and the way information within the “patent” is controlled that is determinative. In re Ekenstam, 256 F.2d 321, 118 USPQ 349 (CCPA 1958). See the next subsection for further explanation with respect to when a document can be applied in a rejection as a “patent.” See MPEP § 2135.01 for a further discussion of the use of “patents” in pre-AIA 35 U.S.C. 102(d) rejections.

Foreign Country Designation of a Document as a ‘Patent’ Is Not Determinative for Rejection Under AIA 35 U.S.C. 102(a)
Note:
The designation of a document as a patent in a foreign country does not qualify it for rejection under the AIA 35 U.S.C. 102(a) if its substance and control of information within do not meet U.S. standards.

Patent Secrecy Does Not Affect Pre-AIA 102(d)
Note:
A period of secrecy after granting a patent does not affect its use as prior art under pre-AIA 35 U.S.C. 102(d).

Even if a patent grants an exclusionary right (is enforceable), it is not available as prior art under 35 U.S.C. 102(a) or pre-AIA 35 U.S.C. 102(a) or (b) if it is secret or private. In re Carlson, 983 F.2d 1032, 1037, 25 USPQ2d 1207, 1211 (Fed. Cir. 1992). The document must be at least minimally available to the public to constitute prior art. The patent is sufficiently available to the public for the purposes of 35 U.S.C. 102(a) or pre-AIA 35 U.S.C. 102(a) or (b) if it is laid open for public inspection or disseminated in printed form. See, e.g., In re Carlson, 983 F.2d at 1037, 25 USPQ2d at 1211 (“We recognize that Geschmacksmuster on display for public view in remote cities in a far-away land may create a burden of discovery for one without the time, desire, or resources to journey there in person or by agent to observe that which was registered under German law. Such a burden, however, is by law imposed upon the hypothetical person of ordinary skill in the art who is charged with knowledge of all contents of the relevant prior art.”). The date that the patent is made available to the public is the date it is available as a 35 U.S.C. 102(a) or pre-AIA 35 U.S.C. 102(a) or (b) reference. In re Ekenstam, 256 F.2d 321, 118 USPQ 349 (CCPA 1958). But a period of secrecy after granting the patent has been held to have no effect in connection with pre-AIA 35 U.S.C. 102(d). These patents are usable in rejections under pre-AIA 35 U.S.C. 102(d) as of the date patent rights are granted. In re Kathawala, 9 F.3d 942, 946, 28 USPQ2d 1785, 1788-89 (Fed. Cir. 1993).

Patents Usable as Pre-AIA Prior Art Upon Granting
Note:
Patents are considered prior art for rejection purposes under pre-AIA 35 U.S.C. 102(d) from the date of patent grant.
