A case review: Davies v Lazer Safe Pty Ltd [2019] FCAFC 65
Naleesha Niranjan reviews a patent infringement case which underlines the importance of construing claims without imparting to them glosses drawn from the specification.
Physics and optical engineering patents
Many products that have made their way into daily life, such as microwaves, medical lasers, nuclear medicine and optical fibre data communications have their roots in developments in the fields of physics and optical engineering. One of the newest fields of physics to be commercialised is quantum mechanics and significant leaps forward in computational power have already been made in quantum computing. Incidentally, one of the leaders in this field, Silicon Quantum Computing, is locally based and a spin-out company from UNSW.
Our patent attorneys have backgrounds in physics enabling us to speak the same language as researchers and to better translate your work into patent assets. We have great depth of experience and work closely with university partners and other commercial enterprises to help protect innovations in the field of physics.
What is or is not patentable in the physics industry?
A common thread throughout patent law worldwide is that fundamental principles of physics are not patentable in themselves. However, the practical application of those same fundamental principles to solve technological, real-world problems lie squarely in the realm of patentable subject matter.
For example, Einstein’s famous principle relation governing the inter-relationship between mass and energy E=mc2, in and of itself would not be patentable in isolation. However, the many practical applications of this relation, such as, nuclear reactors, CT & PET scanners in hospitals or the humble smoke detector are all eminently patentable applications of nuclear physics and quantum mechanics and ultimately, E=mc2.
Benefits and challenges in filing physics patent applications
For researchers, there is a professional requirement to publish papers on their findings. It is important to file a patent application before disclosing an invention publicly via a paper or presentation in order to establish ownership and a competitive edge over other start-ups in the market who may be developing similar concepts concurrently. It is also important to speak with a patent attorney who will ensure the IP protection sought aligns with commercial objectives.
