`
`
`1. My name is Paul Dalby, Ph.D. I have been retained by Mylan
`
`Pharmaceuticals Inc. (“Mylan”) to provide my expert opinions regarding the
`
`unpatentability of U.S. Patent No. 10,335,462 (“’462 patent”) (Ex. 1001). I
`
`understand that Mylan intends to petition for inter partes review (“IPR”) of the ’462
`
`patent, which is assigned to Novo Nordisk A/S. I also understand that, in the IPR
`
`petition, Mylan will request that the United States Patent and Trademark Office
`
`cancel all claims of the ’462 patent as unpatentable. I submit this expert declaration
`
`to address and support Mylan’s IPR petition for the ’462 patent.

`I.
`
`QUALIFICATIONS AND BACKGROUND
`A. Education and Experience; Prior Testimony
`I earned my doctorate at Cambridge University, UK, in 1998 where I
`2.
`
`studied protein folding mechanisms, using protein engineering to alter the relative
`
`stabilities of the native, denatured, intermediate and transition states, and evaluating
`
`the effects of a range of temperature, pH and presence of viscosity modifiers in the
`
`formulation. From 1998 to 2000, I was a postdoctoral fellow at the University of
`
`Pennsylvania, where I studied the relationship between protein structure, stability
`
`and function through protein engineering and biophysical characterisation, and also
`
`methods to improve stability and minimize aggregation in protein therapeutic
`
`formulations. In 2000, I was appointed Lecturer at University College London
`
`(UCL) in the Department of Biochemical Engineering. My research focused on new
`

`DR. REDDY’S LABORATORIES, INC.
`IPR2024-00009

`
`

`

`
`
`
`strategies for evolutionary protein and enzyme design, researching factors to
`
`
`
`strengthen protein stability during biopharmaceutical downstream processes, and
`
`developing stability analysis methods to optimise the process and maintain proper
`
`protein formulation.
`
`3.
`
`From 2004-2006, I was principal investigator on a project funded by
`
`the Department of Trade and Industry in conjunction with the Health Protection
`
`Agency, UK, to establish protein, process, and formulation engineering methods for
`
`novel protein fusions. During that time, I was an active member of the Protein
`
`Society, the Royal Society of Chemistry, the RSC Biotechnology Group Committee,
`
`the Institution of Chemical Engineers, and the American Chemical Society. I
`
`organized conferences on behalf of these organizations including the 2006
`
`“Therapeutic Proteins: Chemical & Enzymatic Modification” in London. Based on
`
`my work with the previous organizations, I was invited to a joint BIA & Bioprocess
`
`UK workshop in 2005. The workshop led to the establishment of biopharmaceutical
`
`formulation as a funding priority in the DTI technology transfer program.
`
`4.
`
`In 2006, I began a long-term collaboration with the National Institute
`
`of Biological Standards and Controls in the UK to improve the tools and techniques
`
`used in liquid and freeze-dried protein formulation development. The projects
`
`undertaken used biophysical analysis and statistical design of experiments

`

`
`
`
`approaches, to optimise formulations, and to characterise and understand the impact
`
`
`
`of different excipients on their properties.
`
`5.
`
`In 2007, I was appointed Senior Lecturer at UCL and in 2009 I was
`
`appointed Reader at UCL in the Department of Biochemical Engineering. From
`
`2011 until 2016, I was Co-Director of the Engineering and Physical Sciences
`
`Research Council (EPSRC) Centre for Innovative Manufacturing at UCL.
`
`6.
`
`I am currently Co-Director of the EPSRC Future Targeted Healthcare
`
`Manufacturing Hub and Director of the EPSRC Doctoral Training Centre for
`
`Innovative Manufacturing at UCL. In 2013, I was appointed Professor at UCL,
`
`Department of Biochemical Engineering, and in 2016 was named Deputy Head,
`
`Department of Biochemical Engineering (Research) at UCL. Over the course of my
`
`career at UCL, I have supervised numerous projects resulting in novel research and
`
`development in the field of protein stability. These projects resulted in developing a
`
`novel method for measuring protein stability in microtiter plates; development of
`
`enhanced bioprocessing for advanced pharmaceutical proteins, using directed
`
`evolution; and new methods of protein engineering and formulation resulting in
`
`improved biopharmaceutical stability. The various projects are listed in my CV. I
`
`have presented the results of my research on protein therapeutics and formulation at
`
`numerous international conferences including the Protein Science Forum 2005, the
`
`Cambridge Healthtech Institute 2006, ACHEMA 2006, BioProcess International

`
`I am considered a key influencer of research priorities in the UK in the
`
`area of biopharmaceutical formulation. I have been appointed to lead government
`
`and industry groups for establishment of biopharmaceutical formulation protocols. I
`
`have provided consultancy services to a number of companies, including:
`
`Ajinomoto, Angel Biotechnology, Cambridge Antibody Technology (now
`
`MedImmune and owned by AstraZeneca), and Clear Capital Ltd. I also serve on the
`
`Scientific Advisory Board for Leukocare GmbH in Germany, and UMabs in the
`
`USA and China, and have presented my work at international conferences on
`
`biopharmaceutical formulation development.
`
`8.
`
`I have been given numerous research grants to research and supervise
`
`projects impacting the biochemical protein industry. My research interests include:
`
`accelerating therapeutic protein and vaccine formulation design for stability in both
`
`liquid and lyophilized forms; biophysical characterisation of protein aggregation and
`
`stability in formulations and bioprocess manufacturing; protein engineering for
`
`stability; using directed evolution, structural analysis, bioinformatics and
`
`computational design, high-throughput bioprocess design, including precipitation
`
`and inclusion body refolding; design and development of novel analytical methods
`
`for bioprocess monitoring and characterisation of formulations.

`
`
`
`SUMMARY OF OPINIONS
`13. My opinions are limited to semaglutide formulations used in the
`
`treatment of diabetes, as claimed in the ’462 patent. I present my opinions from the
`
`perspective of a POSA, who is defined in Section IV.
`
`14.
`
`I understand that Mylan’s expert Dr. John Bantle offers the opinions
`
`that it would have been obvious to a POSA to treat diabetes with a once-weekly, 1.0
`
`mg semaglutide injectable formulation, as recited in the limitations of claims 1–3,
`
`containing the components recited in claims 4–10 (which I address herein), with a
`
`reasonable expectation of success in doing so.
`
`15. Based on my view of the prior art and, for certain claims, Dr. Bantle’s
`
`additional views of the prior art, it is my opinion that the claims of the ’462 patent
`
`would have been obvious over the following combinations of references:
`
`a) Claims 4–10 of the ’462 patent would have been obvious over WO421
`
`considering the ’424 publication (Ground 3) or over NCT657 and
`
`NCT773 considering the ’424 publication (Ground 5); and
`
`b) Claims 4–10 of the ’462 patent would have been obvious over WO537
`
`considering Lovshin (Ground 4).
`
`16. These references would have motivated a POSA to formulate a 1.0 mg
`
`semaglutide injectable formulation containing the components recited in claims 4–
`
`13
`
`MPI EXHIBIT 1007 PAGE 13
`
`DR. REDDY’S LABORATORIES, INC.
`IPR2024-00009
`Ex. 1007, p. 13 of 115
`
`

`

`
`
`
`10 to treat type 2 diabetes, as described by Dr. Bantle (claims 1–10), with a
`
`
`
`reasonable expectation of success doing so.
`
`17.
`
`I understand that Patent Owner may present expert opinions regarding
`
`“secondary considerations” of non-obviousness of the formulations recited in the
`
`method of treatment claims in response to my declaration, and that I may be asked
`
`to address such opinions in the future. I therefore expressly reserve the right to
`
`address later all issues of secondary considerations that Patent Owner’s experts may
`
`raise.
`
`III. LEGAL STANDARDS
`18. To prepare and form my opinions set forth in this declaration, I have
`
`been informed of the relevant legal principles.1 I applied my understanding of those
`
`principles in forming my opinions. My understanding of those principles is
`
`summarized below.
`
`
`1 To support my analysis and to help me reach my opinions and conclusions, I was
`
`informed of and advised to apply various legal principles relating to unpatentability,
`
`which I set forth here. By setting forth these legal standards, I do not intend to testify
`
`about the law. I only provide my understanding of the law, as explained to me by
`
`counsel, as a context for the opinions and conclusions I provide in this case.

`
`

`

`
`
`
`
`19.
`
`I have been informed that Mylan bears the burden of proving
`
`
`
`unpatentability by a preponderance of the evidence. I have been told that this means
`
`it must be more likely than not that the claims are unpatentable.
`
`20.
`
`I understand that my opinions regarding unpatentability are from the
`
`viewpoint of a person of ordinary skill in the art (“POSA”) in the field of technology
`
`of the patent as of the patent’s priority date. I have also been informed by counsel
`
`that when defining a POSA, the following factors may be considered: (1) the
`
`educational level of the inventor; (2) the type of problems encountered in the art; (3)
`
`prior art solutions to those problems; (4) rapidity with which innovations are made;
`
`and (5) sophistication of the technology and educational level of active workers in
`
`the field. Further, I understand a POSA is generally skilled in the relevant art (i.e.,
`
`the subject matter claimed and described in the patent).
`
`21.
`
`I am told that for a patent to be anticipated, a prior art reference must
`
`disclose all elements of that claim expressly and/or inherently as arranged in the
`
`claim. With respect to inherent disclosure, there is no requirement that a POSA
`
`would have recognized the inherent disclosure at the time of the invention, but only
`
`that the subject matter is in fact inherent, or necessarily present, in the prior art
`
`reference.
`
`22.
`
`I am told that the concept of patent obviousness involves four factual
`
`inquiries: (1) the scope and content of the prior art; (2) the differences between the
`
`15

`
`
`claimed invention and the prior art; (3) the level of ordinary skill in the art; and (4)
`
`
`
`secondary considerations of non-obviousness.
`
`23.
`
`I understand that when there is some recognized reason to solve a
`
`problem, and there are a finite number of identified, predictable, and known
`
`solutions, a person of ordinary skill in the art has good reason to pursue the known
`
`options within his or her technical grasp. If such an approach leads to the expected
`
`success, it is likely not the product of innovation but of ordinary skill and common
`
`sense. I understand that any need or problem known in the field of endeavor at the
`
`time of invention or addressed by the patent can provide a reason for combining
`
`prior art elements to arrive at the claimed subject matter. I understand that only a
`
`reasonable expectation of success is necessary to show obviousness.
`
`IV. PERSON OF ORDINARY SKILL IN THE ART
`In my opinion, the following definition of a person of ordinary skill in
`24.
`
`the art applies to the claims of the ’462 patent. I reserve the right to amend and/or
`
`supplement my opinions on unpatentability if a different definition of a POSA is
`
`adopted or agreed to.
`
`25. A POSA would have understood the prior art references referred to
`
`herein and would have the capability to draw inferences from the prior art references.
`
`It is understood that, to the extent necessary, a POSA may collaborate with one or
`
`more other POSAs for one or more aspects with which the other POSA may have

`Ex. 1007, p. 16 of 115
`
`

`

`
`
`
`expertise, experience, and/or knowledge. Additionally, a POSA could have had a
`
`
`
`lower level of formal education than what I describe in the following definition if
`
`the person has a higher degree of experience. In view of the relatively high level of
`
`skill and the clear teachings in the prior art, the level of skill of a POSA is not
`
`dispositive of any issue raised in this Petition.
`
`26.
`
`In my opinion, the following definition of a POSA applies to the claims
`
`of the ’462 patent. A POSA would have (1) an M.D., Pharm.D., or Ph.D. in
`
`pharmacy, chemical engineering, bioengineering, chemistry, or related discipline;
`
`(2) at least two years of experience in protein or peptide therapeutic development
`
`and/or manufacturing or diabetes treatments; and (3) experience with the
`
`development, design, manufacture, formulation, or administration of therapeutic
`
`agents, and the literature concerning protein or peptide formulation and design, or
`
`diabetes treatments.
`
`27. Alternatively, a POSA would be (1) a highly-skilled scientist lacking
`
`an M.D., Pharm.D., or Ph.D., but would have (2) more than five years of experience
`
`in the area of protein or peptide therapeutic development and/or manufacturing or
`
`diabetes treatments; and/or (3) experience with the development, design,
`
`manufacture, or formulation of therapeutic agents, and the literature concerning
`
`protein or peptide formulation and design or diabetes treatments. In either case, a
`

`
`

`

`
`
`
`higher educational level could substitute for some amount of the requisite
`
`
`
`experience.
`
`28. As explained above, and as is evident from my CV, I met the
`
`qualifications of a POSA as of the priority date of the ’462 patent.
`
`V. THE ’462 PATENT (EX. 1001)
`I have read the ’462 patent, which is titled “Use of Long-Acting GLP-
`29.
`
`1 Peptides,” including its claims, and reviewed relevant portions of the file history
`
`of the ’462 patent (Ex. 1002).
`
`30.
`
`I have assumed that the earliest priority date to which the asserted
`
`claims of the ’462 patent are entitled is July 1, 2012, which is the date recited on the
`
`face of the patent for foreign reference EP12174535, listed under “Foreign
`
`Application Priority Data.” To the extent Patent Owner later asserts and/or proves
`
`that the asserted claims are entitled to an earlier priority or invention date, I reserve
`
`the right to supplement this declaration.
`
`A. The Formulation Claims of the ’462 Patent
`31. The ’462 patent has one independent claim, which recites:
`
`1. A method for treating type 2 diabetes, comprising
`administering semaglutide once weekly in an amount of
`1.0 mg to a subject in need thereof.

`
`

`

`
`
`
`
`32. Dependent claims 4–10 depend from claim 1, directly or indirectly, and
`
`
`
`are provided below.
`
`33. Dependent claim 4 recites:
`
`4. The method according to claim 1, wherein the
`semaglutide is administered in the form of an isotonic
`aqueous solution comprising phosphate buffer at a pH in
`the range of 7.0-9.0.
`
`34. Dependent claim 5 recites:
`
`5. The method according to claim 4, wherein the solution
`further comprises propylene glycol and phenol.
`
`35. Dependent claim 6 recites:
`
`6. The method according to claim 4, wherein the pH is 7.4.
`
`36. Dependent claim 7 recites:
`
`7. The method according to claim 6, wherein the solution
`further comprises propylene glycol and phenol.
`
`37. Dependent claim 8 recites:
`
`8. The method according to claim 4, wherein the
`phosphate buffer is a sodium dihydrogen phosphate
`buffer.
`

`
`MPI EXHIBIT 1007 PAGE 19
`
`DR. REDDY’S LABORATORIES, INC.
`IPR2024-00009
`Ex. 1007, p. 19 of 115
`
`

`

`
`
`
`
`
`
`9. The method according to claim 1, wherein the
`semaglutide is administered by subcutaneous injection in
`the form of an isotonic aqueous solution comprising at a
`sodium dihydrogen phosphate buffer at a pH in the range
`of 7.0-9.0, and wherein the solution further comprises
`propylene glycol and phenol.
`
`39. Dependent claim 10 recites:
`
`10. The method according to claim 9, wherein the pH is
`7.4.
`
`B. The Prosecution History of the ’462 Patent
`40. When the application for the ’462 patent was filed on July 21, 2017,
`
`independent claim 1 recited:
`
`1. A method for
`
`a) reduction of HbA1c;
`
`b) treatment of type 2 diabetes, hyperglycemia, impaired
`glucose tolerance, or non-insulin dependent diabetes; or
`
`c) treatment of obesity, reducing body weight and/or food
`intake, or inducing satiety;
`
`wherein said method comprises administration of a GLP-
`1 agonist to a subject in need thereof, wherein said GLP-1
`agonist
`
`i) has a half-life of at least 72 hours;
`
`20
`
`MPI EXHIBIT 1007 PAGE 20
`
`DR. REDDY’S LABORATORIES, INC.
`IPR2024-00009
`Ex. 1007, p. 20 of 115
`
`

`

`
`
`
`
`
`
`ii) is administered in an amount of at least 0.7 mg per
`week, such an amount equivalent to at least 0. 7 mg
`semaglutide per week; and
`
`iii) is administered once weekly or less often.
`
`Ex. 1002 at 8.
`
`41. The Examiner rejected the filed claims on July 23, 2018, based on
`
`NCT00696657, which disclosed the use of semaglutide and liraglutide, Madsbad
`
`(2011), which disclosed the use of several GLP-1 agonists, and Kim (2007), which
`
`disclosed the use of exenatide, anticipated the claims because they each disclosed a
`
`method of treatment with at least 0.8 mg of GLP-1 agonist once weekly (NCT657
`
`with 0.8 mg semaglutide; Madsbad with 4, 15, and 30 mg albiglutide; and Kim with
`
`0.8 and 2.0 mg exenatide), with all the other requirements satisfied (treating type 2
`
`diabetes and reducing HbA1c, with a half-life in the required range, etc.). See Ex.
`
`1002 (July 23, 2018 Office Action) at 312.
`
`42. The applicants then amended claim 1 to recite:
`
`1. (Currently Amended) A method for treating type 2
`diabetes, comprising administering semaglutide once
`weekly in an amount of 1.0 mg to a subject in need thereof
`
`a) reduction of HbA1c;
`
`b) treatment of type 2 diabetes, hyperglycemia, impaired
`glucose tolerance, or non-insulin dependent diabetes; or

`IPR2024-00009
`Ex. 1007, p. 21 of 115
`
`

`

`
`
`
`
`
`
`c) treatment of obesity, reducing body weight and/or food
`intake, or inducing satiety;
`
`wherein said method comprises administration of a GLP-
`1 agonist to a subject in need thereof,
`
`wherein said GLP-1 agonist
`
`i) has a half-life of at least 72 hours;
`
`ii) is administered in an amount of at least 0.7 mg per
`week, such an amount equivalent to at least 0.7 mg
`semaglutide per week; and
`
`iii) is administered once weekly or less often.
`
`See Ex. 1002 (January 23, 2019 listing of claims) at 332.
`
`43. The applicants also filed a terminal disclaimer over U.S. Patent No.
`
`9,764,003, which claims “[a] method for reducing body weight, comprising
`
`administering [only] semaglutide once weekly in an amount of at least 0.7 mg and
`
`up to 1.6 mg to a subject in need thereof.” See Ex. 1002 (February 28, 2019 Terminal
`
`disclaimer) at 336.
`
`44. The Examiner then withdrew the anticipation rejections and allowed
`
`the claims, stating:
`
`The ’657 clinical trial compared semaglutide and
`liraglutide in treatment of type 2 diabetic patients. The
`semaglutide or liraglutide was used as on add-on therapy
