Invention Not Patentable if Previously Publicly Available
Note:
A claimed invention is not patentable if it was available to the public before its effective filing date.

AIA 35 U.S.C. 102(a)(1) provides a “catch-all” provision, which defines a new additional category of potential prior art not provided for in pre-AIA 35 U.S.C. 102. Specifically, a claimed invention is not entitled to a patent if it was “otherwise available to the public” before its effective filing date. This “catch-all” provision permits decision makers to focus on whether the disclosure was “available to the public,” rather than on the means by which the claimed invention became available to the public or whether a disclosure constitutes a “printed publication” or falls within another category of prior art as defined in AIA 35 U.S.C. 102(a)(1). The availability of the subject matter to the public may arise in situations such as a student thesis in a university library (see, e.g., In re Cronyn, 890 F.2d 1158, 13 USPQ2d 1070 (Fed. Cir. 1989); In re Hall, 781 F.2d 897, 228 USPQ 453 (Fed. Cir. 1986); In re Bayer, 568 F.2d 1357, 196 USPQ 670 (CCPA 1978) and MPEP § 2128.01, subsection I.); a poster display or other information disseminated at a scientific meeting (see, e.g., In re Klopfenstein, 380 F.3d 1345, 72 USPQ2d 1117 (Fed. Cir. 2004), Massachusetts Institute of Technology v. AB Fortia, 774 F.2d 1104, 227 USPQ 428 (Fed. Cir. 1985), Jazz Pharm., Inc. v. Amneal Pharm., LLC, 895 F.3d 1347,127 USPQ2d 1485 (Fed. Cir. 2018), and MPEP § 2128.01, subsection IV.); subject matter in a laid-open patent application or patent (see, e.g., In re Wyer, 655 F.2d 221, 210 USPQ 790 (CCPA 1981); see also Bruckelmyer v. Ground Heaters, Inc., 445 F.3d 1374, 78 USPQ2d 1684 (Fed. Cir. 2006)); a document electronically posted on the Internet (see, e.g., Voter Verified, Inc. v. Premier Election Solutions, Inc., 698 F.3d 1374, 104 USPQ2d 1553 (Fed. Cir. 2012), In re Lister, 583 F.3d 1307, 92 USPQ2d 1225 (Fed. Cir. 2009), SRI Int'l, Inc. v. Internet Sec. Sys., Inc., 511 F.3d 1186, 85 USPQ2d 1489 (Fed. Cir. 2008), and MPEP § 2128); or a commercial transaction that does not constitute a sale under the Uniform Commercial Code (see, e.g., Group One, Ltd. v. Hallmark Cards, Inc., 254 F.3d 1041, 59 USPQ2d 1121 (Fed. Cir. 2001) and MPEP § 2133.03(e)(1)). Even if a document or other disclosure is not a printed publication, or a transaction is not a sale, either may be prior art under the “otherwise available to the public” provision of AIA 35 U.S.C. 102(a)(1), provided that the claimed invention is made sufficiently available to the public.

Public Availability Over Other Prior Art Categories
Note:
Decision makers focus on whether the disclosure was available to the public, rather than its specific form or category of prior art.

AIA 35 U.S.C. 102(a)(1) provides a “catch-all” provision, which defines a new additional category of potential prior art not provided for in pre-AIA 35 U.S.C. 102. Specifically, a claimed invention is not entitled to a patent if it was “otherwise available to the public” before its effective filing date. This “catch-all” provision permits decision makers to focus on whether the disclosure was “available to the public,” rather than on the means by which the claimed invention became available to the public or whether a disclosure constitutes a “printed publication” or falls within another category of prior art as defined in AIA 35 U.S.C. 102(a)(1). The availability of the subject matter to the public may arise in situations such as a student thesis in a university library (see, e.g., In re Cronyn, 890 F.2d 1158, 13 USPQ2d 1070 (Fed. Cir. 1989); In re Hall, 781 F.2d 897, 228 USPQ 453 (Fed. Cir. 1986); In re Bayer, 568 F.2d 1357, 196 USPQ 670 (CCPA 1978) and MPEP § 2128.01, subsection I.); a poster display or other information disseminated at a scientific meeting (see, e.g., In re Klopfenstein, 380 F.3d 1345, 72 USPQ2d 1117 (Fed. Cir. 2004), Massachusetts Institute of Technology v. AB Fortia, 774 F.2d 1104, 227 USPQ 428 (Fed. Cir. 1985), Jazz Pharm., Inc. v. Amneal Pharm., LLC, 895 F.3d 1347,127 USPQ2d 1485 (Fed. Cir. 2018), and MPEP § 2128.01, subsection IV.); subject matter in a laid-open patent application or patent (see, e.g., In re Wyer, 655 F.2d 221, 210 USPQ 790 (CCPA 1981); see also Bruckelmyer v. Ground Heaters, Inc., 445 F.3d 1374, 78 USPQ2d 1684 (Fed. Cir. 2006)); a document electronically posted on the Internet (see, e.g., Voter Verified, Inc. v.

Sys., Inc., 511 F.3d 1186, 85 USPQ2d 1489 (Fed.

Hallmark Cards, Inc., 254 F.3d 1041, 59 USPQ2d 1121 (Fed. Cir. 2001) and MPEP § 2133.03(e)(1)). Even if a document or other disclosure is not a printed publication, or a transaction is not a sale, either may be prior art under the “otherwise available to the public” provision of AIA 35 U.S.C. 102(a)(1), provided that the claimed invention is made sufficiently available to the public.

Requirement for Subject Matter Availability
Note:
The rule defines when subject matter is considered available to the public, including through student theses, scientific meetings, patent applications, and more.

AIA 35 U.S.C. 102(a)(1) provides a “catch-all” provision, which defines a new additional category of potential prior art not provided for in pre-AIA 35 U.S.C. 102. Specifically, a claimed invention is not entitled to a patent if it was “otherwise available to the public” before its effective filing date. This “catch-all” provision permits decision makers to focus on whether the disclosure was “available to the public,” rather than on the means by which the claimed invention became available to the public or whether a disclosure constitutes a “printed publication” or falls within another category of prior art as defined in AIA 35 U.S.C. 102(a)(1). The availability of the subject matter to the public may arise in situations such as a student thesis in a university library (see, e.g., In re Cronyn, 890 F.2d 1158, 13 USPQ2d 1070 (Fed. Cir. 1989); In re Hall, 781 F.2d 897, 228 USPQ 453 (Fed. Cir. 1986); In re Bayer, 568 F.2d 1357, 196 USPQ 670 (CCPA 1978) and MPEP § 2128.01, subsection I.); a poster display or other information disseminated at a scientific meeting (see, e.g., In re Klopfenstein, 380 F.3d 1345, 72 USPQ2d 1117 (Fed. Cir. 2004), Massachusetts Institute of Technology v. AB Fortia, 774 F.2d 1104, 227 USPQ 428 (Fed. Cir. 1985), Jazz Pharm., Inc. v. Amneal Pharm., LLC, 895 F.3d 1347,127 USPQ2d 1485 (Fed. Cir. 2018), and MPEP § 2128.01, subsection IV.); subject matter in a laid-open patent application or patent (see, e.g., In re Wyer, 655 F.2d 221, 210 USPQ 790 (CCPA 1981); see also Bruckelmyer v. Ground Heaters, Inc., 445 F.3d 1374, 78 USPQ2d 1684 (Fed. Cir. 2006)); a document electronically posted on the Internet (see, e.g., Voter Verified, Inc. v. Premier Election Solutions, Inc., 698 F.3d 1374, 104 USPQ2d 1553 (Fed. Cir. 2012), In re Lister, 583 F.3d 1307, 92 USPQ2d 1225 (Fed. Cir. 2009), SRI Int'l, Inc. v. Internet Sec. Sys., Inc., 511 F.3d 1186, 85 USPQ2d 1489 (Fed. Cir. 2008), and MPEP § 2128); or a commercial transaction that does not constitute a sale under the Uniform Commercial Code (see, e.g., Group One, Ltd. v. Hallmark Cards, Inc., 254 F.3d 1041, 59 USPQ2d 1121 (Fed. Cir. 2001) and MPEP § 2133.03(e)(1)). Even if a document or other disclosure is not a printed publication, or a transaction is not a sale, either may be prior art under the “otherwise available to the public” provision of AIA 35 U.S.C. 102(a)(1), provided that the claimed invention is made sufficiently available to the public.

Document or Disclosure Not a Printed Publication Can Still Be Prior Art
Note:
A claimed invention is not entitled to a patent if it was made sufficiently available to the public before its effective filing date, even if the document or disclosure is not a printed publication.

AIA 35 U.S.C. 102(a)(1) provides a “catch-all” provision, which defines a new additional category of potential prior art not provided for in pre-AIA 35 U.S.C. 102. Specifically, a claimed invention is not entitled to a patent if it was “otherwise available to the public” before its effective filing date. This “catch-all” provision permits decision makers to focus on whether the disclosure was “available to the public,” rather than on the means by which the claimed invention became available to the public or whether a disclosure constitutes a “printed publication” or falls within another category of prior art as defined in AIA 35 U.S.C. 102(a)(1). The availability of the subject matter to the public may arise in situations such as a student thesis in a university library (see, e.g., In re Cronyn, 890 F.2d 1158, 13 USPQ2d 1070 (Fed.

Cir. 1986); In re Bayer, 568 F.2d 1357, 196 USPQ 670 (CCPA 1978) and MPEP § 2128.01, subsection I.); a poster display or other information disseminated at a scientific meeting (see, e.g., In re Klopfenstein, 380 F.3d 1345, 72 USPQ2d 1117 (Fed. Cir. 2004), Massachusetts Institute of Technology v. AB Fortia, 774 F.2d 1104, 227 USPQ 428 (Fed. Cir. 1985), Jazz Pharm., Inc. v. Amneal Pharm., LLC, 895 F.3d 1347,127 USPQ2d 1485 (Fed. Cir. 2018), and MPEP § 2128.01, subsection IV.); subject matter in a laid-open patent application or patent (see, e.g., In re Wyer, 655 F.2d 221, 210 USPQ 790 (CCPA 1981); see also Bruckelmyer v. Ground Heaters, Inc., 445 F.3d 1374, 78 USPQ2d 1684 (Fed. Cir. 2006)); a document electronically posted on the Internet (see, e.g., Voter Verified, Inc. v.

Sys., Inc., 511 F.3d 1186, 85 USPQ2d 1489 (Fed.

New Category of Prior Art Under AIA 35 U.S.C. 102(a)(1)
Note:
Defines additional types of prior art not covered in pre-AIA 35 U.S.C. 102, focusing on public availability regardless of means.

AIA 35 U.S.C. 102(a)(1) provides a “catch-all” provision, which defines a new additional category of potential prior art not provided for in pre-AIA 35 U.S.C. 102. Specifically, a claimed invention is not entitled to a patent if it was “otherwise available to the public” before its effective filing date.
