California Healthcare Institute Issues White Paper on the Impact of Recent Patent Law Developments

    By Donald Zuhn --

On Thursday, the California Healthcare Institute (CHI), an independent organization comprising more than 250 biomedical companies, academic and research institutions, and companies involved in supporting the biomedical community, released a white paper entitled "Impact of Patent Law Changes on Biomedical Investment and Innovation."  The CHI white paper analyzes the implications of recent patent law developments on the biomedical industry, and concludes that a handful of Supreme Court decisions, Congress' attempt to enact patent reform legislation, and the Patent Office's push for new patent rules have combined to reduce the value of life sciences patents will have a "chilling effect on biomedical investment and innovation."

According to the white paper, the first challenge to the patenting of life sciences inventions comes from the Supreme Court's "apparent growing anti-patent stance," which is reflected in a number of Supreme Court decisions, including: Merck KgaA v. Integra Lifesciences I, Ltd. (2005), eBay Inc. v. MercExchange, L.L.C. (2006), MedImmune, Inc. v. Genentech, Inc. (2007), and KSR Int'l Co. v. Teleflex Inc. (2007).  In particular, the report contends that the Court, in Merck, "weakened the ability of patent holders to enforce their rights against companies performing drug research."  The report also concludes that the Court's decision in eBay, which reduces the availability of permanent injunctions to patentees, "weakens the value of patent rights for patent owners who are not commercializing their inventions by making it more difficult for those parties to enjoin an infringer."  With respect to the MedImmune decision, the report observes that the Court has made it easier for a patent licensee to challenge the validity of a licensed patent.  Finally, the report concludes that the Court's decision in KSR lowers the standards used to evaluate obviousness, thus making it harder for applicants to obtain patents and easier for defendants to invalidate them.

The second challenge to the patenting of life sciences inventions comes from Congress' attempt to enact patent reform legislation.  The report contends that the most recent round of proposed patent reforms reflects fundamental differences in business models of two distinct high-tech industries:  life sciences on one side and software/IT on the other.  The report notes that because life sciences products are long-lived and less susceptible to incremental improvement, and further because investors must be able to rely on patent protection to justify the costs of bringing life science products to market, the relative value of life sciences patents is much higher than the relative value of software/IT patents.

According to the CHI report, the final challenge to the patenting of life sciences inventions comes from the "heavy handed approach taken by the U.S. Patent and Trademark Office (USPTO) towards making and promulgating new patent rules."  The report takes the Patent Office to task for its proposed limitations on the permissible number of claims and continuation applications, contending that such modifications will "significantly change the way applicants file their applications and would decrease an applicant's ability to obtain full patent coverage for its inventions," and predicting that the proposed changes to the rules will "have a devastating effect on mid-sized and start-up life science companies."  The report believes that if the proposed rules changes are implemented, life sciences companies will motivated to accept narrower claims in order to obtain the allowances needed to secure investment funding, or even worse, will be forced into a lengthy appeal process that could preclude investment altogether.

The CHI white paper ultimately concludes that these three areas of change "represent an extensive and dramatic shift that will make patents harder to obtain, easier to invalidate, and cheaper to infringe, thus creating incalculable problems for the life sciences community in procuring and maintaining the essential patent protections for their inventions."

The (As Yet) Unfulfilled Promise of Personalized Genomics

    By Kevin E. Noonan --

One of the many benefits touted by proponents of the Human Genome Project has been the prospect of personalized medicine, based on a determination of an individual's entire genomic DNA sequence.  The advantages of this information are expected to include an understanding about the status of disease propensity-associated genes, as well as the existence of isoforms of enzymes, such as the P450 system in liver, that can affect how efficacious a particular drug may be in the individual, or alternatively, how ineffective or even toxic the individual's reaction to the drug may be.  Since both types of information represent a huge increase in specific knowledge about an individual (as opposed to the statistical data that underlie such determinations at present), the prospect of being able to ascertain this sequence information is widely considered to be the harbinger of a brave new world of 21st century medicine.

Two more steps towards this brighter tomorrow were taken today.  First, and entirely fittingly, Dr. James Watson (at left) was presented with a pair of CD-ROMs containing approximately 3 billion basepairs encoding his genomic DNA.  The presentation was made by Dr. Richard Gibbs, director of Baylor College of Medicine's Human Genome Sequencing Center, and Dr. Jonathan Rothberg, founder of the company 454 Life Sciences.  Dr. Rothberg's company makes the automated DNA sequencing machines that enabled Dr. Gibbs' team to determine Dr. Watson's genomic DNA sequence in months rather than years, and at a cost of less than one million dollars.  It is thought that expected advances in the technology will reduce the cost even further, to perhaps as little as ten thousand dollars; at that point widespread genomic DNA sequencing may become economically feasible.

The Watson DNA sequence will be made publicly available, with one exception:  Dr. Watson will not disclose the sequence of the gene that encodes apolipoprotein E in his genome, since certain alleles of this gene are associated with the development of Alzheimer's disease.

Ironically, another total genomic DNA sequence will also soon become available, that of Dr. J. Craig Venter (at right), the man whose for-profit company, Celera Corporation, is credited with motivating completion of the human genomic DNA sequence (obtained from a mixture of different individual's DNA) by the Human Genome Project, headed by Dr. Watson.

The other announcement came from the National Human Genome Research Institute (NHGRI), involving a study of 1,000 individuals with symptoms of coronary artery disease.  This study is limited to determining the genomic sequence of between 200 and 400 genes known to be associated with this disease, although there will also be an analysis of other genetic variations.  These genomic determinations will take about two years, and will be correlated with changes in disease states of the participants.  The goal is better understanding of the association between disease and genetic variability.

As promising as these efforts may be, there are reasons to be skeptical about them, at least in the short term.  The determination of individual genomes, while informative for the individuals, may not provide any broader information about the "canonical" human sequence, because there is good evidence from classical population genetics that such a sequence does not exist.  In studies done 40 years ago, Richard Lewontin (at right) and others showed that natural populations contain a great deal of genetic variation in the amino acid sequence of common cellular enzymes.  This variation did not appear to confer any evolutionary advantage on the organisms expressing them (typically, Drosophila), leading to what has been called the "neutralist" school of population biologists.  The explanation is that organisms have this vast genetic variability that is neutral under normal circumstances, but provides a reservoir of adaptability during times associated with speciation - natural disasters, isolated sub-populations, and geographic allopatry.  Thus, a determination of any individual's genomic DNA can be expected to say little about "the" sequence for any particular gene; "the" sequence will, at best, be the most common sequence in a population, requiring information from thousands or perhaps millions of individuals to be accurately portrayed.

Another reason for skepticism about projects like the NHGRI's is that it will be limited to the 200-400 genes now known to be associated with coronary artery disease.  By limiting the scope of the study to these genes, the data produced will increase our understanding of the genes, but not perhaps the underlying disease, for example, if there are genes not yet identified that play an unappreciated (and perhaps important) role in the disease etiology.

Finally, the problem with applying genomics in this way is reminiscent of Abraham Maslow's aphorism, that "if you only have a hammer, you tend to see every problem as a nail."  The determination of the human genomic sequence has been a landmark achievement, but caution suggests that the problems of biology are unlikely to be solved in any meaningful way merely by detecting variabilities in DNA sequence.  Certainly these do exist - sickle cell anemia is the result of a transversion (A to T) mutation that changes a valine residue to a glutamic acid residue.  However, clinicians know that there is variability in how different sickle cell anemia patients react to environmental stimuli, reflecting the interactions of the millions of other genes they express.  Systems biologists are just now beginning to explore the relationships between the biological products of genes, proteins and the cellular structures they create.  It is well to be reminded that we are merely at the beginning of this journey, and that the projects announced today are only the smallest of steps to unraveling (to the extent we are able) the fascinating riddle of life.

FDA Grants Approval to UCB & Sanofi-Aventis Allergy Drug

    By Christopher P. Singer --

In a May 29, 2007 press release, sanofi-aventis and UCB announced that the FDA approved Xyzal® (active ingredient: levocetirizine dihydrochloride) a once-daily prescription antihistamine for the relief of seasonal and perennial allergic rhinitis, as well as for the treatment of chronic idiopathic urticaria (hives) in adults and in children age six and older.  UCB filed the new drug application (NDA) in July 2006 and researched the drug in a number of clinical trials.  Xyzal® was shown to reduce the severity of common symptoms associated with allergies, such as runny nose, itchy eyes, and sneezing.  In patients with hives, the drug was able to reduce the number, size, and itch associated with the hives.

In the fall of 2006, sanofi-aventis signed an agreement with UCB in which it agreed to launch and co-market and Xyzal®, which is expected to be ready for launch for the upcoming fall allergy season.

Invitrogen and Clontech Settle Lengthy Patent Litigation

    By Donald Zuhn --

On Tuesday, Invitrogen Corporation and Clontech Laboratories, Inc. jointly announced that the two companies had reached a settlement in a patent litigation battle that had been begun more than 11 years earlier.  Invitrogen had initiated the lawsuit when it filed a complaint against Clontech in December of 1996 in the District Court of Maryland, asserting that Clontech infringed Invitrogen's U.S. Patent Nos. 5,244,797; 5,405,776; 5,668,005; 6,063,608.  Two weeks ago, on May 17, Invitrogen secured a unanimous verdict from the Maryland jury.

As part of the settlement, Clontech, a wholly-owned subsidiary of Takara Bio Inc., has agreed that the four patents-in-suit are valid and enforceable.  In addition, Clontech has agreed to discontinue sales of its RNase H minus RT products, including its PowerScript products, until Invitrogen's patents expire.  No other details of the settlement were announced.

The patents-in-suit encompass a polypeptide having DNA polymerase activity and substantially no RNase H activity ('797 patent), an isolated DNA molecule encoding such a polypeptide ('005 patent), an isolated "DNA compound" encoding such a polypeptide ('776 patent), and an isolated polypeptide having DNA polymerase activity and substantially reduced RNase H activity ('608 patent).

Commenting on the length of the lawsuit, Invitrogen's trial counsel Robert J. Koch of Milbank, Tweed, Hadley & McCloy LLP noted that "[t]he complexity of the underlying science combined with the multiple patents and number of claims involved, contributed to the duration of the litigation" (see "Patent Infringement Victory for Invitrogen").  Over the course of the litigation, the parties had engaged in three District Court battles and had taken three appeals to the Federal Circuit.

Novacea and Schering-Plough to Collaborate

    By Jason Derry --

Novacea, Inc. and Schering-Plough have announced an agreement to develop and commercialize Asentar®, which is currently in Phase III clinical trials for the treatment of prostate cancer.  Novacea is to receive an upfront payment of $60 million and $12 million in common stock.  Novacea may also receive up to $380 million in future royalty payments on sales of Asentar.  The Agreement is subject to clearance under the Hart-Scott-Rodino Antitrust Improvement Act.

Africa (Still) Depending on the Kindness of Strangers in Anti-AIDS Drug Pricing

    By Kevin E. Noonan --

There are new developments in global drug pricing policy today, but while they are good news for sub-Saharan Africa they fall far short of addressing the overarching disaster facing Western drug companies in these disputes (see "Worldwide Drug Pricing Regime in Chaos").

In a move kindly described as charity, The Wall Street Journal reports that Roche Holdings AG announced that it had agreed with two African generic drug companies to transfer technology related to production of the anti-AIDS drug saquinavir "free of charge."  The deal also includes the right for these companies, located in Ethiopia and Zimbabwe, to distribute the drug to any country in sub-Saharan Africa characterized by the United Nations as a "least developed" nation.  Roche also expressed a willingness to enter similar technology transfer agreements under the same terms with other generic drug companies in such countries.

This agreement is one avenue for addressing the economic and political effects of the developing world efforts to reap the benefits of World Trade Organization membership while being able to provide needed drugs for their citizens.  The crisis is particularly acute with regard to anti-AIDS drugs, and in this regard Roche has astutely chosen the countries most affected by the pandemic, and least capable of affording the drugs, to garner the benefits of its charitable largess.  Its actions are also likely to blunt the effectiveness of "more" developed countries, such as Brasil, from establishing markets in such countries for their own generic drug industries.  And by supporting local drug production in Africa, Roche has also began a process for building the types of development relationships that may render these countries' governments less intractable in respecting Roche's patent rights for other, less critically-needed drugs.

The downside of Roche's actions, however, is that they perpetuate the model of Western drug companies treating intellectual property rights as bargaining chips.  They do not address the larger question of resolving the tensions between the once-hoped-for international IP protection regime and resistance to respecting Western drug companies' IP rights when it comes to anti-AIDS and other drugs.  It is possible that deals like the ones Roche has struck with these local drug companies are the best now possible, and insofar as they lessen the pressure of rhetoric (from governments, non-governmental organizations, and even individuals like former President Clinton) to eliminate such IP rights entirely (and have the other benefits mentioned above), they are clearly a coup for Roche.  But they also represent a throwback to the more paternalistic posture of the past, where less developed countries are dependent not on a regulated international system of rights and privileges but on the West's inclinations to act humanely in the face of a crisis (something whose effects can be variable, as seen most recently in Darfur).  They also raise the question of whether Western drug companies, and their governments, have the political will to address the challenges raised by specific actions (like the Doha Declaration and actions taken pursuant thereto by Brasil and others) that most seriously, and systemically, challenge the reigning drug development paradigm.

Michael Crichton's Nightmare: Not Just Talking Monkeys, But Patentable Talking Monkeys

    By Kevin E. Noonan --

The significance of single nucleotide polymorphisms (SNPs) has been appreciated in genetic research ever since the discovery in the early 1980's that SNPs could produce genetic markers known as restriction fragment length polymorphisms (RFLPs).  However, although this type of polymorphism is responsible for well-recognized genetic mutations (for example, in sickle cell anemia, where an A to T transversion mutation changes a glutamic acid to a valine at position six of the amino acid sequence of the  hemoglobin beta-chain), the significance of this type of genetic mutation has been appreciated more than it has been observed - but when observed, such mutations have occasionally been significant (see, for example, U.S. Patent No. 6,051,379).

A striking example of a SNP that alters gene expression and gene product function has been found in a human gene encoding kallikrein-8 (KLK-8).  KLK-8 is a gene expressed in brain and known to be involved in speech and memory.  It was also known that humans differed from mice in producing a splice variant containing an additional 45 amino acids encoded in the intervening sequence adjoining the third exon (which sequence is spliced out in mice but retained in the mRNA produced in human brain tissue).  The significance of this change has been unappreciated, at least in part due to the phylogenetic distance between mice and man.  The analysis of these differences in species closer to man evolutionarily, specifically chimpanzees and other great apes, sheds new light on its significance.

As reported on May 8, 2007 in the online version of Human Mutation, scientists from the Chinese Academy of Sciences have identified a transversion mutation in human KLK-8 gene.  As a consequence, human KLK-8 is alternatively-spliced in human brain tissue, with one of the resulting transcripts being identical to the mouse transcript, and the other having an additional 45 amino acids encoded by exon 3.  In their analysis, these researchers showed not only that the "long form" variant was not expressed in other primates (or any other mammalian species studied), but that the capacity for producing this alternatively-spliced transcript was due to an T to A mutation in the intervening sequence between coding exons 2 and 3.  Other primates do not have this mutation, only humans do (and there is no polymorphism detected among different human racial groups, suggesting this mutation is "fixed" in the human genome), and it can be traced to an event that occurred about 5 million years ago.  The mutation creates a "splicing enhancer" sequence that creates the long form transcript for the first time in primate evolution.

It has been evident for some time that the small overall differences between human and chimpanzee genomic DNA (on the order of 1-2%) could explain the phenotypic differences between the species based not on how many genetic sequence differences there are but on which sequences are different.  The possibilities for genetic differences that are responsible for the species differences include those operating at a histological level (such as chromosomal rearrangements, both local and global, and genetic duplication) and on the genetic level (such as SNPs, alternative splicing, and differential gene expression).  Significantly, human neural tissue exhibits a high level of alternative splicing events, one of the proposed mechanisms that reconcile the phenotypic differences between humans and other primates and the relatively small human transcriptome size (30,000-45,000 genes rather than the anticipated ~100,000 human genes).

The discovery of the KLK-8 mutation, and the existence of transgenic animal technology, suggests the possibility that a transgenic chimpanzee can be produced that expresses the long form of KLK-8 in neural tissues.  Indeed, the only sure way to determine whether this mutation had any effect on neural function would be to make such a transgenic animal.  And this is where it gets interesting (or terrifying, depending on your point of view).  KLK-8 is believed to be involved in the physiological mediation of speech in the brain, and the coincidence of the unique abilities of humans for speech and the existence of the long form mutation raises the possibility that any such transgenic chimpanzee would have an enhanced ability to learn to speak.  Classic attempts to teach other primates to speak (notably, "Nim Chimpsky," at left, in the 1970's) demonstrated that these animals have whatever brain structures or functions are required to be capable of making connections between human words and objects (even emotions).  Thus, a transgenic chimpanzee might be able to speak, and if so, verbal communication with another species could occur for the first time.

The possibilities for bridging the gap in our understanding of how another species thinks are tantalizing.  Other possibilities are less felicitous, including the realization that such a talking chimpanzee is eminently patentable.  U.S. law has a strict prohibition on patenting humans - the 13th Amendment banning slavery - and attempts by Jeremy Rifkin and others to patent human/animal chimeras have been thwarted by administrative decisions in the U.S. Patent and Trademark Office.  (In this regard, the British Department of Health recently reversed a ban on such chimeras, although it has not yet passed the House of Commons.)  There are no such prohibitions against transgenic primate patenting (transgenic animal patent claims usually recite a "non-human" animal), and given the costs of producing such a transgenic chimp, patent protection may be necessary to garner sufficient investment.

Whether the results of these studies will resemble "Dr. Doolittle" or "Planet of the Apes" is, of course, impossible to predict.  However, it is likely that anyone (like author Michael Crichton) who is unconvinced about the wisdom of permitting "patenting life" will be politically opposed, and the extent to which such opposition is persuasive will determine the fate of any attempts to own a talking monkey.

Strafford CLE on Patent Licensing

Strafford CLE Teleconferences will be offering a telephone conference entitled: "Patent Licensing Post MedImmune: Proceed with Caution: Best Practices for Adapting to Sweeping Change in Licensing" on June 28, 2007 from 1:00-2:30 PM (EST).  In January, the Supreme Court rejected the Federal Circuit's long-standing "reasonable apprehension of suit" test in MedImmune v. Genentech, changing the legal landscape for patent licensing.  In late March, the Federal Circuit substantively applied the MedImmune decision for the first time in SanDisk v. STMicroelectronics, holding that a patent owner that asserts infringement against another entity to demand licensing and royalties cannot prevent the alleged infringer from then litigating the merits of these infringement assertions.

In the Strafford teleconference, speakers Allen E. Hoover of Banner & Witcoff, Michael J. Sacksteder of Fenwick & West, and Michael L. Kiklis of Akin Gump Strauss Hauer & Feld will examine the Federal Circuit's first application of the Supreme Court's decision in MedImmune, discuss the impact of this decision on patent holders and licensees, and outline the best practices for IP asset owners in view of these latest developments in patent licensing law.  The speakers will also address questions such as:

• What is the immediate impact of SanDisk for both patent holders and prospective licensees?
• What clues does SanDisk give patent owners and licensees on the continuing development of patent law in the wake of MedImmune?
• How does SanDisk alter how patent holders and licensees should approach patent licensing negotiations and agreements?
• What are the important considerations for pursuing infringement accusations and for filing declaratory judgments?

An interactive Q&A session will follow the speaker presentations.  The registration fee for this telephone conference ranges from $247 (for those registering before June 1) to $297 (for those registering after June 1).  A program outline for the teleconference can be obtained here.  Those interested in registering for the teleconference, can do so here, or by calling 800-926-7926 ext. 10.

PLI CLE on KSR Int'l Co. v. Teleflex, Inc.

Practising Law Institute (PLI) will be offering a webcast on the Supreme Court's decision in KSR Int'l Co. v. Teleflex, Inc. on June 13, 2007 from 1:00-2:00 PM (EST).  The webcast, entitled "The Scope and Implications of the Supreme Court's Ruling in KSR v. Teleflex on the Doctrine of Patent Obviousness," is the fourth installment in PLI's series of Patent Hot Topic Briefings.  Speakers James W. Dabney of Fried, Frank, Harris, Shriver & Jacobson LLP (counsel of record for KSR International), Thomas C. Goldstein of Akin Gump Strauss Hauer & Feld LLP (counsel of record for Teleflex), and moderator Douglas R. Nemec of Skadden, Arps, Slate, Meagher & Flom LLP will discuss the KSR decision and its implications on the prosecution of applications before the U.S. Patent and Trademark Office, on the litigation of patent cases (including the impact of the decision on summary judgment procedures), and in negotiations over potential patent licenses.  According to PLI, the speakers will also cover such issues as:

• The Federal Circuit's anticipated reaction to KSR.
• Additional obviousness issues that remain to be resolved.
• The Supreme Court's approach to patent questions generally.

The registration fee for this webcast is $299.  Those interested in registering for the webcast, can do so here.

Dispute over Fat-Loss Supplement Settles

    By Robert Dailey --

Norwegian biotech Natural ASA has settled its patent infringement suit against ArkoPharma involving conjugated linoleic acid (CLA), a dietary supplement thought to reduce body fat.  Natural markets its CLA product in the U.S. under the trademark Tonalin®.  (A month's supply of Tonalin® gel capsules sells for about $25.)

Natural ASA is the exclusive licensee of two WARF-owned patents: U.S. Patent Nos. 5,554,646 and 5,814,663.  Both patents cover methods of using CLA to reduce and/or maintain body fat in humans.  ArkoPharma had begun selling CLA-containing dietary products in the U.S. without seeking a license from Natural ASA (or Natural's downstream licensees).  Therefore, Natural filed suit last summer in federal district court in Madison, Wisconsin.  Under the settlement agreement, ArkoPharma will begin purchasing its CLA from Natural's licensees (in addition to paying damages for past infringement).

The settlement spells good news for those holding CLA patent portfolios.  The Tonalin® products have become a popular dietary supplement in the U.S. and Europe.  Natural's dominance in this market is sure to continue.  Furthermore, this result should bode well for U.S.-based PharmaNutrients, which is planning to introduce a CLA formulation that reduces atheriosclerotic plaque.

Additional information regarding the settlement can be found here and here.

Patent Profile: Koronis Pharmaceuticals Announces Allowance of HIV Therapeutic Patent

    By Donald Zuhn ---

Last month, Koronis Pharmaceuticals, Inc. announced that the United States Patent and Trademark Office had issued a Notice of Allowance for its application directed to Koronis' lead HIV therapeutic candidate, KP-1461.  The patent that eventually issues from the allowed application will be the first U.S. patent to be awarded to the Redmond, Washington-based biotechnology company.

A search of the USPTO Published Applications database and of Public PAIR indicates that the Notice of Allowance described in Koronis' statement was issued for U.S. App. No. 10/226,799, which is entitled "Mutagenic Nucleoside Analogs for the Treatment of Viral Disease," and which was published on September 11, 2003 as U.S. Patent Application Publication No. 2003/0170872.  The Public PAIR record for this application shows that the Notice of Allowance was mailed on January 11, 2007.  Because the applicants filed a Petition to Revive on January 25, 2007, it is unclear when the patent will issue.

According to the statement released by Koronis, the allowed claims relate to both the use and composition of KP-1461, a small molecule for oral administration that is currently being tested in clinical trials for the treatment of HIV infection.  In a process known as Viral Decay Acceleration (VDA), the novel compound has been shown in in vitro experiments to increase the virus' naturally high mutation rate, with the accumulation of mutations throughout the viral genome ultimately exceeding an error threshold that leads to viral collapse.

The '799 application claims the benefit of U.S. Provisional Application Nos. 60/314,728, filed August 24, 2001.  Representative independent claim 1 of the '799 application recites:
