Natco Withdraws Application for ‘Export’ Compulsory Licenses
Mint has reported that Natco requested Controller of Patents to withdraw its applications for compulsory licenses for export of generic anti-cancer drugs Sunitinib and Erlotinib, both patented in India. Earlier, Natco filed application for compulsory licenses of Erlotinib and Sunitinib to be exported to Nepal under section 92A of the Indian patent law. Though Natco’s move was unprecedented and shocked many but legal equations were never favorable for Natco because there was no official notification made by Nepal Government to allow importation of anti-cancer drugs from India (a litmus test for Indian Patent Office to evaluate compulsory license for export). Whatever may be the reasons for Natco to withdraw its application for compulsory license but what can be concluded from the whole episode that it was a bad patent-legal strategy yet was a good business strategy to keep Natco's script rolling on Bombay Stock Exchange?

Abbott Files Para IV Litigation Against Dr. Reddy's Labs
Abbot Laboratories has filed an infringement lawsuit against Hyderabad-based Dr. Reddy’s Laboratories for the infringement of US Patent Nos. 6,511,678, 6,528,090, 6,713,086 and 6,720,004 following DRL paragraph IV certification as part of an abbreviated new drug application (ANDA) to manufacture a generic version of Depakote ER (divalproex sodium extended release tablet).

Will it be Raining Patent Litigations in India?
Last edition of IDMA Bulletin (Vol. XXXIX No. 25) has interesting piece of advertisement from Cipla announcing brand names of 20 generic drugs likely to be introduce shortly. Just for the information of overseas readers, in India (unlike the US) generic companies sell generic versions under their own brand names. Here also, the list advertised by Cipla is of brand names not generic names so there is always a possibility of error in identifying the exact drug substance from brand name but still few brand names seems to closely resemble the generic names. The list includes brand names like Soranib (resembling Bayer’s anti-cancer drug Sorafenib), Sunitib (resembling Pfizer’s anti-cancer drug Sunitinib), Sprydas (resembling Bristol-Myer’s anti-cancer drug Dasatinib marketed as Sprycel), Lapanib (resembling Glaxo’s anti-cancer drug Lapatinib) and Nilotib (resembling Novartis’s anti-cancer drug Nilotinib). All these anti-cancer drugs belong to the same class of Tyrosine Kinase Inhibitors and for which either patent applications are pending or patents are granted in India (see here). Bristol-Myer has already received the Indian Patent No. 203937 for Dasatinib and last year Delhi Patent Office granted Pfizer the Indian Patent No. 209251 for Sunitinib. If Patent Circle guess about brand names is proper then possibly it will be raining patent litigations in India? It seems to be like Erlotinib (Tarceva), Cipla will again go ahead disrespecting patents for other anti-cancer drugs. Watch out … Roche may have company to join.

Teva Tasting Own Medicine
The world’s largest generic manufacturer Teva Pharmaceutical Industries instead of challenging Innovators’ drug patents will now be defending its own patented drug Copaxone against the Para IV certification made by Momenta and its partner Sandoz. Generically referred as Glatiramer Acetate, Copaxone is an anti-sclerosis drug that had US sales of $ 1.1 billion last year. Glatiramer is a biotech drug and Teva firmly believes that it would be difficult product to replicate and will require full clinical trials to get approval for the generic Copaxone. Teva said it intended to sue Momenta and Sandoz for alleged patent infringement of Orange Book listed patents. There are seven OB listed patents (US 5,981,589, US 6,054,430, US 6,342,476, US 6,362,161, US 6,620,847, US 6,939,539 and US 7,199,098) covering active ingredient Glatiramer Acetate, pharmaceutical compositions containing it, and methods of using it.

Federal Circuit Ruled Against Apotex Reverse Doctrine of Equivalents
The Federal Circuit has disagreed with Apotex that a district court erred in failing to find non-infringement under the reverse doctrine of equivalents and upheld the district court decision granting summary judgment that Roche’s US Patent No. 5,110,493 is valid and infringed by Apotex’s ANDA for generic version of anti-inflammatory eye drug Acular LS. Acular LS is an ophthalmic solution containing ketorolac tromethamine marketed by Allergan for the treatment of inflammation associated with glaucoma, conjunctivitis and eye surgery.
The ‘493 patent claims an ophthalmic formulation comprising a non-steroidal inflammatory drug, a quaternary ammonium preservative, and the non-ionic surfactant, octoxynol 40 (O40). In its Appeal, Apotex did not dispute that its ANDA falls within the literal scope of claim 1 of the ‘493 patent but instead argued that the district court erred in failing to find non-infringement under the reverse doctrine of equivalents. The Federal Circuit explained that the reverse doctrine of equivalents (“RDOE”) “is an equitable doctrine designed to prevent unwarranted extension of the claims beyond a fair scope of the patentee’s invention.” The court referred to Supreme Court’s RDOE test, set forth in the Graver Tank case:
Where a device is so far changed in principle from a patented article that it performs the same or a similar function in a substantially different way, but nevertheless falls within the literal words of the claims, the reverse doctrine of equivalents may be used to restrict the claim and defeat the patentee’s action for infringement.
Apotex argued that the ‘principle’ of the ‘493 patent is “the use of O40 in an amount sufficient to cause the formation of micelles and thereby provide robust stability to the formulation by preventing interactions between ketorolac tromethamine and benzalkonium chloride.” The Federal Circuit disagreed and found no support for this principle in the specification, prosecution history or prior art. According to the Federal Circuit, Apotex relied exclusively on the declaration of its expert and agreed that Apotex failed to make out a prima facie case of non-infringement under the reverse doctrine of equivalents, and therefore summary judgment of infringement was proper. The Federal Circuit also agreed with the district court that Apotex’s invalidity arguments were barred by claim preclusion (e.g., res judicata).

Playing Double Standards?
Often accusing foreign MNCs for ever-greening of patent protection, Cipla has filed fair number of patent applications for new forms of known drug substances such as Alfuzosin, Tolterodine, Perindopril, Citalopram, Fexofenadine, Levosulbutamol, Sibutramine, Topotecan, Clopidogrel, Duloxetine, Montelukast, Olanzapine. Over the years, Cipla has successfully pioneered reverse-engineering of innovator drugs with an ability to launch generic versions within shortest possible time. This business strategy not only made Cipla a preferred choice for cheap generic drugs but also transformed into Billion Dollar Company. Though Cipla lacked any expertise in drug discovery or research but went ahead challenging the validity of Tarceva patent under section 3(d) arguing that Erlotinib is a mere derivative of known drug (Gefitinib). I wonder do reverse-engineering expertise gives sufficient insight to complex drug discovery and make such statement (which essentially requires strong research experience and scientific evidence). It is almost like a chemistry department of third-tier University questioning research ability of premier National Chemical Laboratory (NCL) or Indian Institute of Technology (IIT). Interestingly, Cipla recently got patent for inclusion complex of esomeprazole with cyclodextrin, which technically is a case of frivolous patenting but instead they booked Roche for frivolous patenting of Erlotinib. In India, there seems to be case evolving for ‘differential non-obviousness’ and why not Cipla is not innovator and at their level of expertise any patent application filed by them (though how obvious that is) is non-obvious but when it comes to copying of innovator drugs everything under the sun is obvious.

More Patents for New Forms Issued to Generics
There are some more patents issued by the Indian Patent Office to generic companies for new form of known drug substances.
- Teva Pharmaceutical Industries received Indian Patent No. 210420 for novel hydrate forms of alendronate sodium having water content of 1.35% to 11.7%. Patent was issued last year in October by the Mumbai Patent Office against the application no. 497/MUMNP/2005 which is national phase application of WO 2000/012517. The WO disclosure do not made any data suggesting improved efficacy over the known substance.
- Indian Patent No. 219014 issued to Torrent Pharmaceuticals Ltd. for Form T1 of nebivolol and its pharmaceutically acceptable salts against the mail-box application no. 811/MUM/2004. The patent issued earlier this year in April. Equivalent WO 2006025070 does not disclose any data suggesting improved efficacy over the known form.
- Indian Patent No. 212951 for polymorph Form I and 2 of desloratadine hemifumarate issued to Sandoz against the application no. 139/CHENP/2005 which is national phase application of WO 2004012738. The WO disclosure gives no data suggesting improved efficacy over the known form.
- Indian Patent No. 219489 for amorphous and crystalline forms of losartan potassium issued to Teva Pharmaceutical Industries against the mail-box application no. 1286/DELNP/2004 which is national phase application of WO 2003048135. The WO disclosure does not suggest any data relating to improved efficacy over the known form.

Lipitor Settlement: What Lies Beneath? Part II
Strategically Lipitor settlement seems to be more favorable for Ranbaxy as this provides certainty for Ranbaxy to launch generic product in the
What about 180-day market exclusivity?
Technically the 180-day market exclusivity will trigger soon after the expiration (March 2010) of the genus patent but Ranbaxy, under the terms of the agreement, would delay the launch until November 2011 which would possibly lead to forfeiture of Ranbaxy’s right to 180-day market exclusivity. 21 USC 355 (j)(5)(D) states that if the first applicant fails to market the generic product within 75 days from the date of FDA final approval of ANDA that will lead to forfeiture of 180-day exclusivity period. And in case of forfeiture, any later ANDA applicant may market its generic product upon receiving FDA final approval. Interestingly, if Ranbaxy forfeits its 180-day market exclusivity then the Lipitor generic space will open much earlier than the expected (that is before July 2010). However, it would still not be easy for any generic player to cross hurdles of Pfizer’s polymorphs and amorphous patents and step into Lipitor generic fortune. Pfizer not only litigated its patents strategically but possibly put an end to prized 180-day market exclusivity.
Lipitor Settlement: What Lies Beneath?
Historical patent litigation between world’s largest drug manufacturer Pfizer and world’s most aggressive generic company Ranbaxy over biggest ever blockbuster drug Lipitor has finally ended in unexpected climax with both Pfizer and Ranbaxy settling all their patent litigations worldwide. Under the agreement, Pfizer voluntarily licensed Ranbaxy to sell generic versions of Lipitor in the
Pfizer’s Strategy was Ranbaxy’s Dilemma
It all triggered when Ranbaxy filed an abbreviated new drug application (ANDA) with the United States Food and Drug Administration seeking marketing approval for generic equivalent of Lipitor before the expiration of Orange Book listed patents. Pfizer sued Ranbaxy within statutory timelines (45 days) and filed civil action for alleged infringement in the District Court. During the course of litigation proceedings, Ranbaxy strongly challenged the validity of the
Patent Circle believes that Pfizer strategically litigated Lipitor against Ranbaxy and kept polymorph and amorphous patents out of Para IV litigation so that Pfizer may unfold them in separate litigations. Pfizer not only used patents against Ranbaxy but also in parallel strategically filed a citizen petition with the United States FDA regarding amorphous atorvastatin. In its petition, Pfizer concerned about higher levels of impurities and inferior stability of other polymorphs and amorphous forms that may be used by generic companies. Pfizer also stated that the pending application for a generic version is in an amorphous form (though not mentioned the name of company but was possibly referring to Ranbaxy ANDA). In March 2008, Pfizer extended its strategy by filing fresh infringement suit against Ranbaxy for infringement of two non-orange book listed patents – US 6,087,511 and US 6,274,740 both covering processes for the preparation of amorphous Atorvastatin which suggest that Ranbaxy possibly used amorphous atorvastatin calcium for their proposed ANDA. The process patents are due to expire in July 2016 and would mean that if Pfizer succeeds in wining the litigation that would delay Ranbaxy’s generic product till 2016. This litigation put Ranbaxy in dilemma whether to launch generic soon after the expiration of genus patent with a possible risk of treble damages or wait till litigation get over but that may possibly risk of running out 180-days market exclusivity without even launching the generic product for which Ranbaxy played such a risky game. Pfizer’s Strategy was Ranbaxy’s Dilemma.

Cipla Patents Salt and Complex of Blockbuster Drug Substances in India
Mumbai-based Cipla has lately obtained patents for new form of two blockbuster drug substances, namely, esomeprazole and alendronate. In past, Cipla has constantly accused foreign MNCs for ever-greening of patent monopoly and strongly opposed patenting of so-called trivial improvements but in general practicing the same in
Often public health interest organizations criticized patenting of polymorphs or other forms of known substances (considering such improvements as trivial modifications) and keep targeting foreign MNCs of being patent freaks but why avoided same practice against the Indian companies. The only reason they may give that the foreign MNCs will charge excessive price for patented drugs whereas domestic companies will not. Interestingly last year Cipla received Government notice demanding Rs. 24.23 crore for alleged overcharging on antibiotic ciprofloxacin during the period April 2006 to March 2007. Earlier Cipla also received similar notices from the National Pharmaceutical Pricing Authority (NPPA) demanding as estimated Rs. 941.92 crore for alleged overcharging till March 2006 for five drugs, namely, Salbutamol, Theophylline, Ciprofloxacin, Norfloxacin and Cefadroxil. Just note this overcharging is for generic drugs what if Cipla start marketing and pricing patented drugs. Anyhow bottom line of any business is profit (not public health) and it seems difficult to predict whether NGOs are more confidants to Indian generic companies or to public.

Indian Generics & Health Activists Having Problem Over Patent Titles
Business Standard reported that domestic drug companies and public health activists have accused research-based multinational drug companies of not providing clear information about the type or use of the potential new medicines in patent applications. Also accusing the practice of using complex chemicals, or molecular formulae, in place of clear indicators as patent titles as an attempt to hide the identity of the actual molecule. A Mumbai-based patent expert said, “There are instances of patent title merely mentioning the invention as ‘a novel compound’ or a ‘new pharmaceutical substance’. By doing so, the companies are trying to avoid detection of the actual nature of their products. The Indian patent law has, in fact, considered this factor while saying (in section 10) that the title of the patent application and the patent abstract that follows should describe the product, its use and explain its contents.” Further adding, “However, these rules are often broken than followed.” Addressing the issue, the Indian Pharmaceutical Alliance (IPA) insists that all applications for pharmaceutical substances should indicate the
Every year, the list of problems by domestic drug companies and public health activists seems to be increasing. Earlier, they had problem with (1) introduction of patent protection for pharmaceutical and drug products, (2) (triggering) period for compulsory license, (3) patent office issuing patent for mail-box drug applications (without giving hearing during pre-grant opposition) and latest is patent titles. I too search and track Indian patents/published applications for drug compounds/pharmaceutical products but surprisingly never faced any confusion/difficulty in locating through patent titles. In most of the cases where patents are issued for salts and polymorphs,
There is no point in accusing MNCs for such issue. They provide whatever they feel appropriate but under section 10 (4)(d) of the Patents Act, 1970 the Controller of Patents also have an option to amend the abstract for providing better information to third parties. If MNCs fails in providing abstract in a manner to facilitate searching then it is duty of Controller to do so (or ask applicant to do so).

Press Release: National IPR Campaign Announced
The rapidly growing relevance of intellectual property in the present knowledge driven economic development has led the Government to take several initiatives both in the legislative domain as well as the administrative set-up to create a modern and efficient Intellectual Property infrastructure in the country. Recognizing the critical importance of IP systems for the growth of Indian Industry and to create larger public awareness and further enhance the capacities of Indian patent office and enforcement authorities, FICCI and Department of Industrial Policy and Promotion (DIPP), Government of India have launched “National IPR Campaign”. Under the Campaign, FICCI and DIPP will jointly conduct seminars, workshops and specialized training programmes over a period of one year from April ’08 to March ’09. The Campaign would include awareness programmes on Intellectual Property issues; capacity building Programmes for enforcement authorities and the staff of Controller General of Patents, Designs and Trade Marks (CGPDTM); specialized orientation programmes for patent office examiners; programmes on sensitizing judiciary on speedy and quality adjudication of Intellectual Property cases; continuos advertisements in electronic and print media on “protecting IP and the consequences of violating IP Rights”; establishment of “Knowledge and Education Centres” at all Patent Offices; targeted programmes for stakeholders with a view to shift the current practice of filing patent/trademark applications from paper to electronic mode etc. The campaign will not be limited to big cities alone but will also be taken to tier II and III cities including Baddi, Meerut and Jaipur by FICCI.
