IPR Overview
6
IPR Essential Features
• Claim construction: Broadest reasonable interpretation (“BRI”)
• Grounds for unpatentability limited to patents and printed publications
• Must file within one year of service of complaint for infringement
• Barred if DJ action regarding validity was filed before IPR petition
• Burden of proof: Preponderance of the evidence
• Limited discovery
• Very limited ability to amend claims
• Fast relative to reexamination and district court litigation
• Estoppel (any ground raised or that reasonably could have been raised)
• Can be settled
![Page 7: Cross-Border Patent Issues in the Life Sciences · PDF fileCross-Border Patent Issues in the Life Sciences April 5, ... •Must file within one year of service of complaint for infringement](https://reader034.vdocuments.us/reader034/viewer/2022051723/5ab6b8f77f8b9a0f058e2b83/html5/thumbnails/7.jpg)
PGR - What is it?
• Additional grounds not available in IPR/CBM
• §102 and §103 on printed publications -- but also
• §101
• §112 (written description, enablement, indefiniteness -- but no best mode);
• Double patenting;
• Inventorship; and
• Prior use
• More severe estoppel – any ground that petitioner raised or reasonably could have raised – applied to all grounds, above.

PTAB Decisions—Objective Evidence – Patent Owner Wins

Innopharma Licensing, Inc., et al., Mylan Pharmaceuticals, Inc. and Mylan, Inc. v. Senju Pharm. Co.,
Ltd., Bausch & Lomb, Inc., and Bausch & Lomb Pharma Holdings, IPR2015-00902, Paper No. 90
(PTAB July 28, 2016)
• Claims covered a liquid preparation for ophthalmic use comprising: (1) bromfenac (type of NSAID) and (2) tyloxapol in an amount “sufficient to stabilize” bromfenac
• Petitioner challenged claims as obvious over the combination of two references (Ogawa and Sallman)
• Ogawa disclosed ophthalmic compositions containing bromfenac and polysorbate 80. Both tyloxapol and polysorbate 80 were non-ionic surfactants.
• Sallman disclosed the use of tyloxapol as a solubilizer for a different NSAID in an ophthalmic composition.
• Final written decision: Petitioner failed to prove that any of the claims were unpatentable
• Objective evidence of nonobviousness was key to decision!

Innopharma Licensing, Inc., et al., Mylan Pharmaceuticals, Inc. and Mylan, Inc. v. Senju Pharm. Co.,
Ltd., Bausch & Lomb, Inc., and Bausch & Lomb Pharma Holdings, IPR2015-00902, Paper No. 90
(PTAB July 28, 2016)
• Unexpected results evidence: experimental results showing tyloxapol increased bromfenac stability significantly better than polysorbate 80. Expert witness explained test results and significance.
• Commercial success evidence: showed that success of commercial product (Prolensa) falling within claims was due to stabilizing effect of tyloxapol and ability to eliminate burning and stinging associated with other eye drops. PTAB: “The fact that Prolensa replaced such prescriptions suggests commercial success.” Paper 90, p. 20.
• Industry acclaim evidence: Expert testimony “supported by objective evidence” describing benefits of Prolensa, praise by leading doctors, and praise in peer-reviewed medical journals.

Innopharma Licensing, Inc., et al., Mylan Pharmaceuticals, Inc. and Mylan, Inc. v. Senju Pharm. Co.,
Ltd., Bausch & Lomb, Inc., and Bausch & Lomb Pharma Holdings, IPR2015-00902, Paper No. 90
(PTAB July 28, 2016)
• PTAB credited objective evidence of nonobviousness in concluding
that claims would not have been obvious:
“Taking account of the objective indicia of non-obviousness, including
Patent Owner’s significant evidence of unexpected results, we are not
persuaded that Petitioner demonstrates sufficiently that the combined
disclosures of Ogawa and Sallmann, when considered in light of the
asserted background prior art references, establish the obviousness of
the claimed invention. Petitioner’s proposed substitution of
tyloxapol for polysorbate 80 produced a surprising and
unexpected stabilizing effect on bromfenac. The other objective
indicia of non-obviousness flow from that surprising results.”
Paper 90, p. 72 (emphasis added).

PTAB Decisions—Objective Evidence – Petitioner Wins

Coalition for Affordable Drugs II LLC v. NPS Pharmaceuticals, Inc., IPR2015-01093, Paper No. 67 (PTAB October 21, 2016)
• Kyle Bass hedge fund filing
• Claims covered L-histidine stabilized drug formulations of glucagon-
like peptide-2 (“GLP-2”) and GLP-2 analogs (sold by Shire as
GATTEX®).
• Claims set forth several combinations of GLP-2 peptides and
peptide concentrations, pH levels, L-histidine concentrations, and
different bulking agents and concentrations.
• Claims challenged as obvious on 4 related grounds. Issue was
whether it would have been obvious to formulate GLP-2 analogs
with histidine and mannitol (bulking agent/excipient).
• PTAB found all claims unpatentable under § 103.

PTAB Decisions—Objective Evidence – Petitioner Wins
25
Coalition for Affordable Drugs II LLC v. NPS Pharmaceuticals, Inc., IPR2015-01093, Paper No. 67 (PTAB October 21, 2016)
• Patent owner presented objective evidence of nonobviousness:
unexpected results, commercial success, and satisfaction of long-felt
need.
• PTAB was not persuaded.
![Page 26: Cross-Border Patent Issues in the Life Sciences · PDF fileCross-Border Patent Issues in the Life Sciences April 5, ... •Must file within one year of service of complaint for infringement](https://reader034.vdocuments.us/reader034/viewer/2022051723/5ab6b8f77f8b9a0f058e2b83/html5/thumbnails/26.jpg)
PTAB Decisions—Objective Evidence – Petitioner Wins
26
Coalition for Affordable Drugs II LLC v. NPS Pharmaceuticals, Inc., IPR2015-01093, Paper No. 67 (PTAB October 21, 2016)
• Unexpected results: Patent Owner presented bar graphs
illustrating heat stress stability studies. PTAB concluded that
results were NOT unexpected:
“[W]e determine that a preponderance of the evidence demonstrates
that an ordinary artisan would have expected the addition of
histidine to improve the stability of a protein formulation, at least
to some degree, based on the disclosures [of the prior art].”
Paper 67, p. 29.
• PTAB further held that even if results were unexpected, they were
not probative of nonobviousness because any differences in stability
improvement were “a difference in degree, not kind.” Id., p. 30.

PTAB Decisions—Objective Evidence – Petitioner Wins
27
Coalition for Affordable Drugs II LLC v. NPS Pharmaceuticals, Inc., IPR2015-01093, Paper No. 67 (PTAB October 21, 2016)
• Commercial success: Patent Owner presented evidence of large
market share, high price, sales and sale growth, and large economic
returns for GATTEX®.
• PTAB held that Patent Owner failed to establish a nexus
between GATTEX® sales and patent claims:
“[I]t is unclear if the sales are due to the stability of the product,
or to the active agent, which is disclosed [by the prior art].”
Paper 67, p. 32.

PTAB Decisions—Objective Evidence – Petitioner Wins
28
Coalition for Affordable Drugs II LLC v. NPS Pharmaceuticals, Inc., IPR2015-01093, Paper No. 67 (PTAB October 21, 2016)
• Long-felt need: Patent Owner presented evidence that GATTEX®
was the first approved GLP-2 product for short bowel syndrome.
• PTAB held that Patent Owner failed to establish a nexus
between the alleged long-felt need and the patent claims:
“Patent Owner does not provide evidence sufficient to permit a
determination as to whether the long-felt need was met by the
discovery of GLP-2 analogs having the necessary activity
(disclosed in the prior art), or the use of L-histidine and mannitol
or sucrose in a stabilized GLP-2 analog formulation.” Paper 67, p.
33.

Teva Pharm. USA, Inc. v. Indivior UK Ltd., IPR2016-00280, Paper No. 23 (PTAB June 10, 2016)
• Claims directed towards an orally dissolvable film that included
buprenorphine, naloxone, a buffer, and a polymer carrier matrix.
Film had a bioequivalent release profile and drug absorption as a
Suboxone® tablet.
• Petitioner raised four grounds of unpatentability based on §103.
Each ground included the “Suboxone® 2002 label” and the
“Suboxone® Table Summary Basis of Approval” (“SBOA”) as
secondary references.
• PTAB declined to grant the petition.
• PTAB held that Petitioner failed to establish that either the
Suboxone® 2002 label or the SBOA was a printed publication.

Teva Pharm. USA, Inc. v. Indivior UK Ltd., IPR2016-00280, Paper No. 23 (PTAB June 10, 2016)
• Petitioner argued that in co-pending litigation, Patent Owner stipulated that both the Suboxone® 2002 label and the SBOA were prior art to the patent at issue. Petitioner offered no further evidence that either was a printed publication.
• PTAB held Petitioner failed to meet its threshold burden of demonstrating that either was a printed publication:
(a) Petitioner filed no exhibits, such as a court document, from the district court case relating to the stipulation;
(b) The stipulation alone is insufficient to meet the threshold requirement because parties may have had others reason to stipulate to the issue;
(c) The petition lacked any information “directly related” to whether either the label or the SBOA were actually publicly accessible in the relevant timeframe. Paper 23, p. 10.

PGR – Institution Denied – Pharma
Dr. Reddy’s Laboratories v. Helsinn Healthcare S.A., PGR2016-00008; U.S. Patent 9,173,942; §102 and §112
• Petitioner – asserted grounds including lack of w/d and violation of on-sale bar provision of §102
• PTAB – denied institution:
• §112 -- “it is undisputed that the specification describes formulations comprising the same ingredients, in the same amounts, concentrations, and combinations required by the challenged claims. Given this disclosure, one of ordinary skill in the art could hardly fail to recognize a description of the claimed formulations in the specification, whether or not the claims recite that the formulations are stable.”
• §102 – “Petitioner has established that MGI’s Form 8-K SEC filings and Helsinn’s press releases made public the existence of the Supply and Licensing Agreements, but Petitioner has not shown that the heavily redacted SEC filings or the press releases, devoid of detail, made the claimed invention available to the public. Thus, we determine that the Supply and Licensing Agreements did not make the claimed invention available to the public one year prior to the critical date at issue here.”
• §103 – no expectation that prior art reference [Tang] would have been effective at treating emesis; “If anything, Tang would have suggested amounts and concentrations still higher than the highest dose and concentration evaluated by Tang.”

minutes] is very limited compared to the broad scope of the claims [from 25oC to
1300oC with no duration]; even inventor expressed questions about the specific
temperatures required --- would therefore require undue experimentation
• Lack of adequate written description – the claimed genus is not supported by the
species disclosed [in Example 4]
• §102 – asserted reference was prior art as claims were not entitled to priority claim
[see above]

Zhang v. Gene Technology Co., Ltd
Invalidation Decision No.23948 (PRB September 22, 2014); (2015) Jing Zhi Xing Chu No. 33 (Beijing
IP Court ); (2016) Jing Xing Zhong No. 1762 (Beijing High Court, July 20, 2016)
• Claims covered a product and method for treating breast cancer with composition of anti-ErbB2 antibody, wherein the composition was contained in a package with a label on it to instruct the patient to avoid using anthracycline antibiotics-type chemotherapeutics in combination with the composition.
• Petitioner challenged claims as obvious over a reference Jose Baselga, which disclosed an animal experiment on nude mice wherein the composition of rhuMoAb HER2 antibody (anti-ErbB2 antibody) was used for treating xenografted human breast cancer tumors.
• PRB decision: all claims were deemed obvious as the PRB found the instruction on the package label does not constitute effective limitation
![Page 46: Cross-Border Patent Issues in the Life Sciences · PDF fileCross-Border Patent Issues in the Life Sciences April 5, ... •Must file within one year of service of complaint for infringement](https://reader034.vdocuments.us/reader034/viewer/2022051723/5ab6b8f77f8b9a0f058e2b83/html5/thumbnails/46.jpg)

IP Court ); (2016) Jing Xing Zhong No. 1762 (Beijing High Court, July 20, 2016)
• The main distinguishing elements between the patent and Jose
Baselga were:
• The patented composition was contained in a package with a
label on it to instruct the patient to avoid using anthracycline
antibiotics-type chemotherapeutics in combination with the
composition;
• Jose Baselga only disclosed an experiment on nude mice rather
than a treatment on a human.

IP Court ); (2016) Jing Xing Zhong No. 1762 (Beijing High Court, July 20, 2016)
• Patentee argued that the patent was non-obvious:
• Jose Baselga did not explicitly break the routine method of using
the anthracycline-type chemotherapeutics to treat breast cancer;
and
• Jose Baselga did not provide any clue on the side effect of using
the anti-ErbB2 antibody in combination with the anthracycline
antibiotics-type chemotherapeutics.

IP Court ); (2016) Jing Xing Zhong No. 1762 (Beijing High Court, July 20, 2016)
• PRB found in its invalidation decision that the patent “lacked
prominent substantive features and significant progress”:
• The essential objective of the patent was to provide a packaged
drug convenient for patients to take;
• The distinguishing element regarding a label providing drug
using instruction was common practice in the filed;
• The prior art provided sufficient inspiration for persons with
ordinary skills in the art to achieve the patent in light of Jose
Baselga; and
• The patent did not disclose any unexpected technical results of
the patent compared with Jose Baselga.

IP Court ); (2016) Jing Xing Zhong No. 1762 (Beijing High Court, July 20, 2016)
• Beijing High Court sustained the invalidation decision and further
emphasized in its final judgment that:
• The instruction on the label was purely about how to use the
drug, which would not change the physical structure or
composition of the drug;
• The limitation about how to use the drug should not be
considered when construing the scope of a claim regarding the
manufacturing of the drug; and
• The use of a package to contain the anti-ErbB2 antibody and
putting a label on the package to specify drug indication and
using instruction was common practice in the art and it was
obvious to persons with ordinary skills in the art.

FU lei v. Beida Pharmaceutical Co., Ltd. Invalidation Decision No. 27258
(October 9, 2015)
• Claims covered a fused quinazoline derivative as a tyrosine kinase inhibitor, as well as their synthesis and use in the treatment of tyrosine kinase-modulating diseases.
• Petitioner challenged, among other invalidation grounds, that the claims were amended beyond the scope of initial disclosure during the prosecution process, as the added elements regarding non-aromatic ring and heteroatom were not explicitly disclosed in the original application documents.
• PRB decision: the amendment of the claims did not go beyond the initial disclosure, as the added elements were indirectly disclosed by the original application documents and the specific elements can be deduced based on the guidance of the embodiments.

PRB Decisions—Amendment of Claim
52
FU lei v. Beida Pharmaceutical Co., Ltd. Invalidation Decision No. 27258
(October 9, 2015)
• During the prosecution process, the Patentee added three elements
to the “A” ring in Claim 1:
• The “A” ring is a 9-membered to 15-membered ring;
• The “A” ring is a non-aromatic monocyclic ring; and
• The “A” ring comprises at least two oxygen atoms and 0 to 3
heteroatoms selected from oxygen, sulfur or nitrogen.
• The element regarding the 9-membered to 15-membered ring was
disclosed explicitly in the text of the original application documents,
while the elements related to the non-aromatic monocyclic ring and
heteroatoms were not clearly disclosed.
![Page 53: Cross-Border Patent Issues in the Life Sciences · PDF fileCross-Border Patent Issues in the Life Sciences April 5, ... •Must file within one year of service of complaint for infringement](https://reader034.vdocuments.us/reader034/viewer/2022051723/5ab6b8f77f8b9a0f058e2b83/html5/thumbnails/53.jpg)
PRB Decisions—Amendment of Claim
53
FU lei v. Beida Pharmaceutical Co., Ltd. Invalidation Decision No. 27258
(October 9, 2015)
• Petitioner alleged that the amendment related to the non-aromatic monocyclic ring and heteroatoms were beyond the initial disclosure as none of them were explicitly recorded in the text of the original application documents.
• Patentee argued that:
• The embodiments in the specification listed a large number of compositions wherein the A rings were non-aromatic monocyclic rings; and
• The persons with ordinary skills in the art could deduce the number of the heteroatoms based on the type of A ring and the content of Claim 12, wherein the heteroatom were 2-5 atoms selected from oxygen, sulfur and nitrogen.

PRB Decisions—Amendment of Claim
54
FU lei v. Beida Pharmaceutical Co., Ltd. Invalidation Decision No. 27258
(October 9, 2015)
• The PRB found the amendment did not go beyond the scope of
initial disclosure:
• Claim 12 already disclosed the A ring could have 2~5
heteroatoms selected from oxygen, sulfur and nitrogen, which
was an upper concept of the element “2 oxygen atoms and 0~3
atoms selected from oxygen, sulfur and nitrogen”;
• Most compositions disclosed by the embodiments were non-
aromatic monocyclic rings; and
• The added elements, though not explicitly recorded in the initial
disclosure, were actually a small part of the larger concept
disclosed by the original application documents.

• Adding an element not explicitly recorded in the original
application document will not necessarily go beyond the initial
disclosure scope.
• Such addition can be accepted as long as the added element
can be ascertained as part of the invention completed prior to
the application date.
