EP Patent Validation Service

Traditional route

The conventional route for EP patent validation is for the client to instruct their EP attorneys to execute the validation. The EP attorneys would then instruct a validations provider (like us) or perform the validations themselves using attorney partners in each country who they use based on a reciprocity model, which is usually not cost or quality selective. The EP attorneys would add significant fees for each country.

About our EP Patent Validation service : Why you should go with us.

Benefits of using our EP validation service :

By using a centralised validations provider like us, the client is cutting out one extra layer of cost, which is usually the most significant cost layer. All large patent filers in Europe use a centralised provider like our associate company because of benefits like the following:

Reduced Risk

We with our European team are specialists in European Patent Validation, which means there is a significantly reduced risk of misunderstanding, unexpected costs, or of course the unthinkable risk of accidental loss of a patent due to the complex and constantly changing regulations around Europe.

Reduced Cost

Validation is a significant part of the cost of a European Patent lifecycle, especially if many countries are required. Filing tens of thousands of validations per year, and translating millions of words into every language, means that ours buying power is enormous. We provide user-friendly and extremely efficient processes to our agents and suppliers which further reduce their costs, and all of this means we are able to pass on these savings to our customers.

New patent, Opicapone, WO 2019123066, Unichem

WO-2019123066

https://patentscope.wipo.int/search/en/detail.jsf?docId=WO2019123066&tab=PCTDESCRIPTION

Process for the preparation of opicapone and its intermediates, useful for treating parkinson's disease. Bial-Portela has developed and launched opicapone, for treating Parkinson's disease.

Opicapone is a selective and reversible catechol-O-methyltransferase (COMT) inhibitor, use as adjunctive therapy for parkinson’s disease. Opicapone was approved by European Medicine Agency (EMA) on June 24, 2016 and it is developed and marketed as ONGENTYS® by Bial-Portela in Europe. Opicapone is chemically described as 2,5-dichloro-3-(5-(3,4-dihydroxy-5-nitrophenyl)-l,2,4-oxadiazol-3-yl)-4,6-dimethylpyridine-l-oxide and depicted below as compound of formula (I).

Opicapone and a process for preparation of it is disclosed in US 8,168,793. The process disclosescondensation of 3, 4-dibenzyloxy-5-nitrobenzoic acid with (Z)-2, 5-dichloro-N'-hydroxy-4, 6-dimethylnicotinimidamide in presence of N, N’-Carbonyl diimidazole in N, N’-dimethylformamide. The crude condensation intermediate was subjected to tetrabutylammonium fluoride (TBAF) mediated cyclization in tetrahydrofuran to give l,2,4-oxadiazole derivative, purifying it by precipitating in 1:1 mixture of dichloromethane: diethyl ether and recrystallized it in isopropyl alcohol. Oxidation of l,2,4-oxadiazole compound is carried out using 10 fold excess of urea hydrogen peroxide complex and trifluoroacetic anhydride in dichloromethane and was purified by column chromatography. Obtained N-oxide compound was converted into opicaponecompound of formula (I) by deprotection O-benzoyl groups by exposure it to boron tribromide (BBr3) in dichloromethane at -78°C to room temperature. Final product was purified in mixture of toluene and ethanol. Above synthetic stepsare outline in scheme 1.

c eme

This process has several drawbacks like cyclization reaction involve use of TBAF and THF. Use of expensive TBAF, leads to high cost in the production and therefore uneconomical for industrial production, whereas use of THF during this reaction has limitation due to peroxide contents. . Similarly diethyl ether is a potential fire hazard and can form peroxides rapidly and thus should be avoided in commercial scale production. Above cyclization is also carried out in presence of DMF and CDI at l20°C.

Similar approach was reported in W02008094053 which describes preparation of opicapone by one pot cyclization of 3,4-dibenzyloxy-5-nitrobenzoic acid with (Z)-2,5-dichloro-N'-hydroxy-4,6-dimethylnicotinimidamide using N,N'-Carbonyl diimidazole in N,N'-dimethylformamide followed by heating the reaction mixture at l35°C for 5 hours to obtain l,2,4-oxadiazole derivative. This oxadiazole derivative was purified by recrystallization from isopropyl alcohol. Further oxidation using urea hydrogen peroxide complex followed by o-debenzylation using boron tribromide (BBr3) was achieved to obtain Opicapone.

This process also suffers from drawback like use of elevated temperature (l35°C) and use of expensive BBr3.

US 9,126,988 also disclose process for the preparation of opicapone, whichinvolves several chemical steps: 1) nitrating vanillic acid in presence of nitric acid in acetic acidfollowed by recrystallization with acetic acid to get nitro compound with yield 40-46%; 2)which converted into acid chloride compoundby treating it with thionyl chloride in presence of catalytic amount of N, N-dimethylformamide in dichloromethane or l,4-dioxane; 3) condensing acid chloride compound with (Z)-2, 5-dichloro-N'-hydroxy-4, 6-dimethylnicotinimidamide in presence of excess amount of pyridine in N,N-dimethyl acetamide/ tetrahydrofuran/ dichloromethane or l,4-dioxane at 5-10 °C and then heating the reaction mixture at H0-l l5°C for 5-6 hours to get 1,2,4-oxadiazole compound; 4) which was oxidized using urea hydrogen peroxide complex and trifluoroacetic anhydride in dichloromethane to get N-oxide product which was purified by repeated recrystallization (2 or more times) using mixture of formic acid and toluene to get pure product with 59% yield; 5) O-methyl group was deprotected using aluminium chloride and pyridine in N-Methyl pyrrolidone at 60 C to obtain opicapone. After completion of reaction, the crude product was isolated by quenching the reaction mixture in mixture cone. HC1: water followed by filtration, washing with water: isopropyl alcohol and recrystallization from ethanol. Final purification was done in mixture of formic acid and isopropyl alcohol. Above synthetic steps are outline in scheme 2.

Scheme 2

As described above, cited literature processes suffers from some drawbacks like elevated reaction temperature and longer duration, use of excess amount of pyridine for cyclization reaction which is difficult to handle on large scale preparation. Another drawback of reported procedure is unsafe workup procedures for isolation of N-oxide as residual peroxides were not quenched by any peroxide quenching reagent. Also repeated crystallizations (more than two) are required for purification of N-oxide derivative to remove unreacted starting material which is tedious and time consuming process. Also for its purification mixture of solvent i.e. formic acid and toluene are used which hamper its recovery and is not cost effective process.

US 9,126,988 also disclosed process for the preparation of 2,5-dichloro-N'-hydroxy-4,6-dimethylnicotinimidamide compound of formula (IV), in which 2,5-dichloro-4,6-dimethylnicotinonitrile compound of formula (VIII) was reacted with hydroxyl amine solution in the presence of catalytic amount of 1,10-phenanthroline in methanokwater at 70-80°C for 6 hrs. After completion reaction mixture was cooled, filtered and dried to get 2,5-dichloro-N'-hydroxy-4,6-dimethylnicotinimidamide of formula (IV) (88%).

Bioorganic & Medicinal Chemistry 13 (2005) 5740-5749, Karl Bailey et.al. disclosed process for preparation of 3,4-dimethoxy-5-nitro benzoic acid compound of formula (Ilia). In which a solution of Cr03, concentrated H2S04 and water was added to solution of 3,4-dimethoxy-5-nitro benzaldehyde in acetone and water. The obtained solution was stirred for 24 hrs and then isopropanol was added to eliminate any unreacted Cr(VI) species to obtained crude green sludge, which was extracted into ethyl acetate and washed with 1M HC1 to remove remaining Cr(III) species. Obtained product is then recrystallized from water and ethanol to yield 69 % of 3,4-dimethoxy-5-nitro benzoic acid compound of formula (Ilia).

US 5,358, 948 also disclosed process for preparation of 3,4-dimethoxy-5-nitro benzoic acid compound of formula (Ilia). In which a solution of potassium permanganate was added to a solution of 3,4-dimethoxy-5-nitro benzaldehyde in acetone. The mixture was then stirred at 20°C for 18 hrs togives 3,4-dimethoxy-5-nitro benzoic acid compound of formula (Ilia) with 72% yield.

Disadvantage of the above cited literature (Karl Bailey et.al and US’ 948) processes are harsh, acidic condition and involve expensive reagents. The process is both uneconomical and time consuming, (18-24 hrs) hence not suitable for commercial production.

Oxidation of aldehydes to the corresponding carboxylic acids, on the other hand, are commonly carried out using KMn04 in acidic or basic media, or K2Cr207 in acidic medium or chromic acid. These heavy metal-based reagents are hazardous and the protocols produce metal wastes that require special handling owing to their toxicities.

It is therefore, desirable to provide efficient, robust, alternative simple process, cost effective process which is used on a large scale and allows product to be easily workup, purified and isolate without the disadvantages mentioned above.

GUEST POST, POOJA KUMAR, CURRENT SCENARIO OF PATENTS IN INDIA

CURRENT SCENARIO OF PATENTS IN INDIA

By Ms. Pooja Kumar

(Registered Patent agent/Director of Innove Intellects)

Email id: pooja@innoveintellects.com

Patent is a monopoly, exclusive rights given to an individual or a company or an organization to make, sell, use and import an invention for a limited period of years. In India patents are granted to inventions that meets three important criteria namely novelty, inventive step and industrial applications. Patents can be given to either product or process. The product can be a device or apparatus or any formulations.

Over the years in India, people are getting serious about the protection of intangible property. And this can be observed by the below mentioned graph:

The WTO is the governing body at the international level, which covers Trade Related Aspects
of Intellectual Property Rights (TRIPs) and several allied agreements. The World Intellectual
Property Organization (WIPO) is another international organization that helps and ensures the
rights of creators and owners of Intellectual Property are protected worldwide and that inventors
thus, recognized and rewarded for their ingenuity.
PATENTS IN THE INDIAN SCENARIO:

The laws pertaining to Patent in India is governed by the Patents Act, 1970 which has been
amended twice by The Patents (Amendment) Act, 1999 and The Patents (Amendment) Act,
2002.
Now-a-days, India has become one of the top patent filers in the world. This graph shows the
efforts of our government and the people who take the initiative to aware people about
Intellectual Property rights (IPR). Indian government has started various startup schemes which
led to the 12-fold increase in the establishment of startups in last year. India, which has 1.6
million active trademarks, registered a total of 339,692 new one last year, 287,139 from domestic
and 52,553 of foreigners, according to the WIPO. Also, government has been provided different
facilities such as early publication, expedited examination, online filing procedures, online
hearings, etc to make the procedure of getting patent easier. Recently, Indian Oil Corporation
emerges as the one of the top patent filing organization in India.
Patent applications are divided into one or more types by the patent office, and as per Indian
Patent Office, a patent applicant can type multiple kinds of patent applications. The documentary
requirements and other formalities for each patent application type are different, and hence it is
crucial to identify the exact type of patent application before initiating the patent filing process.
While filing for a patent, few things are to be considered. The first is which type of application
you are filling. In patents, there are five types of patent applications:
(a) Ordinary Application is the application which is made at the Patent Office for grant of
patent and does not contain any priory claims of application made in any convention country or
countries.
(b) Convention Application is a subsequent application made under Section 135 of the Patent
Act, 1970, claiming the priority date on the application which was filed earlier, where applicant
has already filed an application for grant of patent in a convention country or countries.
(c) PCT Application stands for Patent Cooperation Treaty. The Patent Cooperation Treaty
(PCT) is an international patent law treaty, concluded in 1970. It provides a unified procedure for
filing patent applications to protect inventions in each of its contracting states/countries. The
applicant gets 30-31 months’ time to enter into these countries for getting protection on its
invention, wherein such an application is called PCT National Phase Application. In addition,
patent applicants can file a PCT International Application, either with the Indian Patent Office as
Receiving Office, or directly with International Bureau (IB) of the World Intellectual Property
Organization (WIPO).
(d) Divisional Application is filed under two circumstances:
When the applicant believes that his/her application contains more than one invention and the
other inventions can be differentiated from the original application and filed as a separate
application.

When the controller of patent is of the opinion that the application contains of claims for more
than one invention.

STEPS INVOLVED PATENT FILING TO GRANT:
1. The Filing of an application for grant of a patent accompanied by either a provisional
specification or a complete specification.
2. In case provisional specification accompanies the original application, then filing of the
complete specification within 12 months from the date of filing of the provisional
specification.
3. After the expiry of 18 months time the patents get published on Indian patent office journal.
4. Filing of examination request can be made on form 18 within 48 months from the date of
filing.
5. The patent office send FER response to the applicant and the said response should filed
within 6month of time period.
6. Pre grant opposition can be applied by any interested person after publication and before
grant of patent.
7. Finally Grant and sealing of the patent.
8. Renewal or Maintenance fees paid by the applicant after the grant of patent

BENEFITS OF PATENTS FOR STARTUPS
Patents have become the yardstick for growth for the startup industry. Disruptive start-ups are
currently challenging the incumbent industries with their patented ideas. Having a patent in their
name helps the startups to get noticed in the industry and also helps in securing funding from
potential investors. In 2015, the Government of India announced its flagship initiative of
“Startup India” and offered various incentives for businesses that drives entrepreneurship and
innovation. The key takeaway points from the initiative are as follows:
 Simplifying the startup process with Single Window Clearance through a mobile app
 Fund of funds with a total corpus Rs 10,000 crore (Covered for four years)
 Compliance based Self-certification
 Start-up India hub – A single point of communication for the entire Startup ecosystem
 Patent protection – Fast track mechanisms for start-ups patent applications
 Exception from Capital Gain Tax and tax on earnings for three years)

 Exemption from tax for incubators investing above Fair Market Value

The Patents Act, 1970 has also made special provisions for startups and small entities via the
amendment done in 2016. Rule 24C allows for expedited examination of patent applications, if
the applicant is a small entity or a startup. For a company to be recognized as a startup, it must
satisfy the following criteria:
 The company is enrolled as a Private Limited company
 Its age should not be more than five years
 Its turnover has not exceeded INR 25 crore in any financial year
 It is working towards innovation, development, and commercialization of new product or
services driven by technology
 It has not been formed by reconstruction of an existing business already in operation or as
a subsidiary.

PATENTS AND PHARMACEUTICALS
Since India became a TRIPS member in 1995, the Government of India had to amend the India
Patent Act, 1970. Prior to 2005, product patents were not allowed, only patents to novel
processes were granted and that too for a period of only 14 years. This all changed after 2005,
when the new act allowed the product patents especially of pharmaceutical products and the term
of patent was extended up to 20 years.
A pharmaceutical patent claim may cover any one of the following:
 Active ingredient (API) independently
 API along with formulations, isomers, salts, prodrugs etc
 A manufacturing process
 A manufacturing process and a product
Since the amendment of 2005, it has been difficult for foreign pharmaceutical companies to get
their drugs patented in India, since the majority of the inventions have been slight alterations of
the already existing drugs. Section 3(d) of the Indian Patents Act, 1970 forbids against such
“evergreening” of drugs as is evident from the Novartis case. In 2013, after decades long battle,

the Supreme Court promptly upheld the decision of the lower court and the patent office by
saying that the invention was a slight modification of the known drug (disclosed in 1993) and
that the company did not provide enough evidence to distinguish it from the prior art. This
stringent patent laws have allowed the development of generic drugs, which the people from
even the lower socio-economic groups can afford.
