Examiner May Use Entire Specification for Rejection
Note:
The examiner can consider the entire patent specification, not just claims, when making a rejection under 35 U.S.C. 102(a), (b), or (d).

When the patented document is used as a patent and not as a publication, the examiner is not restricted to the information conveyed by the patent claims but may use any information provided in the specification which relates to the subject matter of the patented claims when making a rejection under 35 U.S.C. 102(a) or pre-AIA 35 U.S.C. 102(a), (b) or (d). Ex parte Ovist, 152 USPQ 709, 710 (Bd. App. 1963) (The claim of an Italian patent was generic and thus embraced the species disclosed in the examples; the Board added that the entire specification was germane to the claimed invention and upheld the examiner’s pre-AIA 35 U.S.C. 102(b) rejection.); In re Kathawala, 9 F.3d 942, 28 USPQ2d 1785 (Fed. Cir. 1993) (The claims at issue were rejected under pre-AIA 35 U.S.C. 102(d) by applicant’s own parent applications in Greece and Spain. The applicant argued that the “invention… patented in Spain was not the same ‘invention’ claimed in the U.S. application because the Spanish patent claimed processes for making [compounds for inhibition of cholesterol biosynthesis] and claims 1 and 2 were directed to the compounds themselves.” Id. at 944, 28 USPQ2d at 1786. The Federal Circuit held that “when an applicant files a foreign application fully disclosing his invention and having the potential to claim his invention in a number of ways, the reference in section 102(d) to ‘invention… patented’ necessarily includes all disclosed aspects of the invention.” Id. at 945-46, 28 USPQ2d at 1789.).

Specification Can Support Claims Under 102
Note:
The examiner can use the entire specification of a patent, not just claims, to reject claims under 35 U.S.C. 102.

When the patented document is used as a patent and not as a publication, the examiner is not restricted to the information conveyed by the patent claims but may use any information provided in the specification which relates to the subject matter of the patented claims when making a rejection under 35 U.S.C. 102(a) or pre-AIA 35 U.S.C. 102(a), (b) or (d).

Invention Fully Disclosed in Foreign Application
Note:
When an applicant files a foreign application fully disclosing the invention, the reference to 'invention… patented' under section 102(d) includes all disclosed aspects of the invention.

When the patented document is used as a patent and not as a publication, the examiner is not restricted to the information conveyed by the patent claims but may use any information provided in the specification which relates to the subject matter of the patented claims when making a rejection under 35 U.S.C. 102(a) or pre-AIA 35 U.S.C. 102(a), (b) or (d).

Specification May Be Used to Reject Claims
Note:
The examiner can use any information in the specification, not just claims, when making a rejection under 35 U.S.C. 102(a) or pre-AIA 102(b).

Claims Must Cover Same Invention
Note:
The claims in a U.S. application must cover the same invention as claimed in a foreign patent, including all disclosed aspects of the invention.

When the patented document is used as a patent and not as a publication, the examiner is not restricted to the information conveyed by the patent claims but may use any information provided in the specification which relates to the subject matter of the patented claims when making a rejection under 35 U.S.C. 102(a) or pre-AIA 35 U.S.C. 102(a), (b) or (d).

Interpretation of Invention Patented in Pre-AIA 35 U.S.C. 102
Note:
The courts interpret the phrase 'invention… patented' uniformly across pre-AIA 35 U.S.C. 102(a), (b), and (d) regardless of which subsection is at issue.

The courts have interpreted the phrase “invention… patented” in pre-AIA 35 U.S.C. 102(a), (b), and (d) the same way and have cited decisions without regard to which of these subsections of pre-AIA 35 U.S.C. 102 was at issue in the particular case at hand. Therefore, it does not seem to matter to which subsection of pre-AIA 35 U.S.C. 102 the cases are directed; the court decisions are interchangeable as to this issue.
