Drug Patent Search – Chemical Patent Attorney

IP Strategy for Drug Patent Search

As reported by WSJ, facing mounting criticism by President Trump about prices, drug companies have put some limits on their increases this year. As it is well known, prescription-drug makers traditionally raise list prices in January. This year, they didn’t raise prices for as many drugs as last year and imposed fewer boosts of 10% or greater, according to an analysis by the investment firm Raymond James & Associates.

New Drug Development – Patent Protection

As drugmakers pushed back against rising criticism over sky-high U.S. prescription drug prices, one pharmaceutical company went public with a pledge. Brent Saunders, CEO of Botox maker Allergan PLC, last September announced a new “social contract” under which the company would limit annual list price increases for its drugs to below 10 percent. Mr. Saunders stated that limiting price hikes forces companies to stay sharp and competitive in innovation and operational excellence. Specifically, pharmaceutical companies stay focused on their pipeline with (patent expirations) in mind, so if their big drug’s patent is ending, they need to formulate three to four R&D programs that, if successful, can cover such patent expiration and provide growth.

Strategy for Drug Patent Search

Traditionally, product and process patents in pharmaceutical sector are obtained with special emphasis on chemical structure patent search technique to determine the patentability of the pharmaceutical drug. Performing a structure based chemical search ensures broadest list of patent results. For example, review the patent search string below. The second drug patent search string provides more than sixteen thousand results for a drug molecule say “X”. Combining the CHEM (chemical structure based search) with other key string parameters can be helpful to perform the drug patent search.

Following example illustrates different parameters to consider while performing drug patent search (Molecule “Y”) for pharmaceutical medicine:

Pharmaceutical Patent Process

Once the patent search is conducted to determine the novelty of the drug process and product (medicine) before filing for patent, laboratory tests are performed to determine synergistic properties of the medical composition and collect scientific data for the same. This process is highly regulated and different countries follow distinctively comprehensive procedure for the same.

Thereafter, patent claims are written to cover both the process of manufacturing the drug and associated medicine products are claimed in separate patent applications. Subsequently, the scientific data description illustrating the synergistic properties of the medical composition in the patent application is provided to regulatory authorities and corresponding patent applications are filed along with request of examination, in accordance with the local patent laws.

Pharmaceutical Products’ Manufacturing – Indian Perspective

The end goal of research and patent grant is to provide affordable medicines to everyone in India. There is a compulsory licensing clause that has been used to allow manufacturing of patented products at affordable prices in public interest in India. Section 84 is applicable and an application for compulsory license on a patent can be made if reasonable requirements for the public with respect to the patented invention have not been satisfied, or if the patented invention is not available to the public at a reasonably affordable price.

Over the years, the Indian legal system has strictly followed the patent law and working requirements of patents in India. The approval of compulsory licensing for a drug is an exception rather than a rule. If a compulsory license of manufacturing a drug is granted by the Indian patent office, a royalty is paid to the patent holder (on agreeable terms between two parties). In recent years, the drug approval process in India has been expedited to keep up with the public demand and provide affordable healthcare to individuals. The Indian pharmaceutical law is now more clear and defined. To know more about drug patent expirations in 2017: click here.

International Patent Filing in India FAQ

Does an International Patent Application filed under Patent Cooperation Treaty (PCT) designating India be treated as a patent application for grant of patent under the Indian Patent 1970 Act?

Yes, an international patent application filed under Patent Cooperation Treaty (PCT) designating India shall be treated as a patent application for patent under the Indian Patent Act if filed within 31 months from the earliest priority date of the patent application before the Indian Patent Office.

Will filing a patent application under PCT grant worldwide patent protection?

No, the Patent Cooperation Treaty (PCT) patent application doesn’t provide universal or worldwide protection for a claimed invention. The international patent application only provides interim way out to extend the time line for filing the patent application in other foreign countries. The time available under Paris Convention for securing priority of the patent application in other countries is 12 months from the date of initial filing. Under the Patent Cooperation Treaty (PCT), the time available could be as much as minimum 20 and maximum 31 months in case of India. Moreover, a patent inventor is also benefited by the international search report prepared under the PCT system to be sure that the claimed patent invention is novel and non-obvious to a person skilled in the art. The patent inventor can also select for preliminary examination before filing in other foreign countries to be very positive about the patentability of the claimed invention.

US-based Intellectual Property Owners’ Association delegation will be meeting the Indian intellectual property office (IPO) officials

US-based Intellectual Property Owners’ Association (IPOA) delegation will be meeting the Indian intellectual property office (IPO) officials, Intellectual Property Appellate Board (IPAB) members, judiciary and judicial staff of high courts. It would be interesting to note the outcome of the meetings. However, it would be interesting to note whether the US pharma lobby will be able to influence the way India’s patent offices and judiciary interpret India’s patent law.

India amended its patent act in 2005 to comply with World Trade Organisation (WTO) agreement to introduce pharmaceutical patents protection for 20 years on medicines. However, in the interest of public health and providing affordable healthcare across the globe the Indian patent act included provisions like section 3(d) to prevent pharmaceutical companies from seeking patent extensions by modifying existing drugs and stop patent evergreening process. Over the years, numerous Intellectual Property Owners’ Association (IPOA) member entities have challenged section 3d. 

In my view meeting with the patent officials will provide the Intellectual Property Owners’ Association (IPOA) members better overview on how to draft the pharmaceutical patent applications to be filed in India. The pharma and medicine based innovations should include data related to therapeutic efficacy to obviate section 3d of the Indian Patent Act. However, it is surprising to note that the Intellectual Property Owners’ Association (IPOA) members are being allowed to meet the judiciary. In a recent case the Supreme Court seriously viewed the allegation of 2G scam accused and coal scam accused meeting the CBI director Ranjit Sinha.

Patent Term Extensions and Supplementary Protection Certificate for Pharma Patents

Supplementary Protection Certificate and Patent Term Extensions for Pharma Patents 

Owing to specific life term of patents, patent expirations have significant commercial impact. In case of pharmaceutical patents, due to expiry of patents pertaining to famous drugs, sales worth billions of dollar are endangered every year.

As fist published on LinkedIn

patent term extensions (PTE) Supplementary Protection Certificates (SPC) European countries

Patent protection and patents extension strategies are equally important for pharmaceutical companies. Major goal of pharmaceutical companies is to build strong patent portfolios and subsequently monetize the same.

Pharmaceutical companies employ patent extension strategies to compensate for their R&D investments and regulatory approval costs of new drugs.

Broadly, three major extensions and protections exist, namely, Supplementary Protection Certificates (SPCs), Patent Term Extensions (PTEs), and Regulatory Data Protection (RDP).

One of the main reasons why companies intend for both market exclusivity and regulatory exclusivity is that there exist significant delays between the filing of pharmaceutical patent and approval of marketing authorization. Accordingly, pharmaceutical companies aim to safeguard their innovation efforts by securing balance with generic competitors.

Usually, various jurisdictions have different legal provisions to extend patent rights. Among the three major extensions and protections, Supplementary Protection Certificates (SPCs) are applicable for Europe (EP), Patent Term Extensions (PTEs) are applicable for jurisdictions including United States (US), Japan (JP), Taiwan (TW) etc.

A broad difference between Regulatory Data Protection (RDP) and patent protection is that while RDP protects the compound (active ingredient) that receives market authorization, patent protection is intended for compounds that are defined within the scope of corresponding claims, which may include derivatives, uses, formulations, synthetic processes etc.

Patent protection is generally aimed at stopping infringers from manufacturing, selling, using or importing claimed invention, whereas RDP protects direct or indirect use of clinical data filed in support of market authorization.

Latest legal developments and decisions effect companies strategies to enhance their patent portfolios. For example, companies in European region need to carefully study the impact of major SPC decisions in cases pertaining to Georgetown University, Actavis, Eli Lilly, and the like. Similarly, developments relating to Unitary Patent, Unified Patent Court and latest US patent reforms could also affect such strategies.

Companies should therefore carry out cross-jurisdictional analysis of various legal provisions and latest regulatory developments to plan advantageous extensions of pharmaceutical patents.
