The Delhi High Court in a crisp, well reasoned, 13 page Order dated 19th April, 2010, has dismissed an interim injunction application in a patent infringement suit filed by Asian Electronics Ltd. v. Havells India Ltd. The patent at suit is unfortunately not available on the IPIRS system. Both Asian Electronics and Havells India are big players in the Indian electronic markets. While Asian Electronics was led by Mr. Gaurav Barathi, who is also counsel for NATCO in its patent dispute with Roche, Havells India Ltd. was represented by Ms. Neha Kapoor. The presiding Judge was Mr. Justice Ravinder Bhat, one of the leading IP judges of the Delhi High Court, as is once again demonstrated through this Order.(a) Details of the Patent
Patent Application No.: No.544/BOM/1999
Patent No: 193488
Date of Grant: 27.02.2007
Inventor: Suresh Hiralal Shah (Chairman of Asian Electronics Ltd.)
Patentee: Asian Electronics Ltd.
Abstract: “Conversion Kit to change the fluorescent lighting units inductive operation to electronic operation”.
Number of other countries where such a patent has been granted: 26
(b) Brief description of the claimed invention
The invention aims at converting fluorescent lighting units, such as tube-lights, from working on an inductive operation mechanism to an electronic operation mechanism without the need for any re-wiring. According to the Plaintiff company, its inventors discovered that fluorescent lighting units operating on an inductive operation mechanism were 'energy inefficient' as they used to flicker while starting and also discharge invisible gas.
The conversion kit invented by the Plaintiffs is claimed by the suit patent in the following manner:
Claim No.10
Conversion kit to change the fluorescent lighting units – from inductive operation to electronic operation as claim in claim 1 comprising alternatively as a modification.
“a. straight fluorescent lamp having at least two contact pins at its each end
b. first and second adaptors mountable on the ends of said lamp, each said adaptor having a pair of internal contacts for mating with said lamp contact pins and also having a pair or external contact pins for mating with contacts in the lighting fixture;
c. connection lines provided in a line channel for electrically connecting the said first adaptor to the said second adaptor; and
d. an electronic ballast.”
The Plaintiff company claims that when it bought and dismantled the Defendant company's product, it discovered that almost all the essential features of its patented invention had been literally copied by the Defendant i.e. (i) The Conversion kit (ii) Adaptors on either side of fluorescent lamp (iii) Wiring assembly & (iv) Ballast.
(c) The Defendant's arguments
The Defendant's put forth four main defenses:
(d) Justice Bhat's Order: Justice Bhat starts of his excellent analysis of the case by noting that the Plaintiffs are not claiming an invention in any of the individual components of the conversion kit. Instead he rightly notes that the invention was claimed for a conversion kit which comprised of several individual components such as the adaptors, the ballast etc.
In the backdrop of this observation he then reviews certain basic concepts of the Indian Patent Act such as the definitions of 'invention', 'inventive step', 'new invention' & 'patent' as also the scope of Section 3 which defines what is not patentable subject matter. In particular he stresses of Section 3(f) which states that the mere arrangement or re-arrangement or duplication of known devices each functioning independently of one another in a known way is not patentable subject matter. The Judge also makes reference to the bar of Section 3(d) which states that a mere use of a known process, machine or apparatus unless such known process results in a new product will not be considered to a patentable invention.
The judgment then carries out a very concise review of English case law on the grant of patents for combination and the “law of collocations”, both of which state the same concepts that are found in Section 3(d) and Section 3(f) i.e. no patent can be granted for the mere re-arrangement of known components unless such re-arrangement leads to a radically different result i.e. not obvious to a person skilled in the art. In light of the statutory provisions, as also the weight of common law, the Judge made a prima facie finding of not only obviousness but also one of non-patentability on the basis of Section 3(d) and Section 3(f).
The Court also found the suit patent to be anticipated by the prior U.S. Patent cited by the Defendant since that one document described the entire invention that was being claimed by the suit patent.
Although the above findings were more than enough to dispose the interim injunction application the Court went ahead to state that by not filing any documents to show the working of the suit patent, the Plaintiff had failed to even demonstrate that the patent was being worked in the Country. On this count the Court found even the balance of convenience in favour of the Defendant company and dismissed the application for interim injunction. A note of warning therefore to all future patentees would be to file statements of working along with interim injunction applications, failing which, it is likely that the Delhi High Court would not find the balance of convenience in the favour of the patentee.
