Inventions are typically an apparatus, a product or a
manufacturing process. Often they can be monopolised by means of
patents, but by no means always. Commercial success in exploiting an
idea or using know-how to create opportunities requires legal advice
which is informed, well-presented and works for your business. This is
the service our solicitors aim to provide.
Key patents-related services offered by our solicitors include:
The patent system
A patent is 20-year monopoly right to work an invention. Its justifications are:
UK patent law is set out in the
Patents Act 1977 as amended (PA 1977). The
Act gives effect to the European Patent Convention 1973 (EPC) and
Revised EPC 2000 and the Patent Co-operation Treaty 1970 (PCT). It also contains provisions that will give
effect to the Community Patent Regulation, if and when that latter
measure comes into force.
Routes
for
obtaining UK patent protection There are two types of UK patent:
These can be obtained by filing an application with the
UK-IPO, the EPO or under the PCT.
A European Patent (EP) can be applied for in other EPC countries (presently 39 including extension States) in addition to the UK. The EP system is cost-effective over independent national filings where patents are sought in at least three European jurisdictions. Once an EP is granted it becomes a bundle of national patents; in the case of an EP (UK) governed by the PA 1977. Revocation of an EP in one country does not affect the validity of the EP in the others. However, for nine months after grant, an EP is subject to opposition in the EPO. A successful opposition means the EP is lost in all the designated countries. The PCT is administered by WIPO in Geneva, www.wipo.org.
An international application is made through a "receiving
office" (the UK Intellectual Property Office is one, as is the EPO)
listing the PCT countries in which protection is sought.
WIPO does not itself substantively examine the application but
communicates the application to the patent offices of the designated
parties, which decide whether to grant patent protection according to
local laws. Any resulting patent is a
national patent. The PCT can be used for
EP applications.
A UK resident must usually file an EP
or PCT application through the UK Patent Office where the information
relates to the military national security (s.23 PA 1977).
For a national patent application this
is set out in ss. 1 – 4A PA 1977. An
invention is patentable if:
(a) the
invention
is new;
(b) it involves an inventive step; (c) it is capable of industrial application; (d) it is not excluded subject matter. All these terms derive from the EPC. Infringement
and
defences to infringement of UK patents
The first question is whether the
invention is a product or a process. This
is determined from the wording of the patent claims.
An invention for a product is infringed by making, disposing of, offering to dispose of, using, importing, or keeping for disposal or otherwise a product falling within the claims of the patent (s. 60(1)(a) PA 1977). An invention for a process is infringed by using the process or knowingly offering it for use, and disposing of, offering to dispose of, using, importing or keeping for disposal or otherwise a product obtained directly from the patented process (s. 60(1)(b) and (c) PA 1977). Contributory infringement is committed where the defendant supplies or offers to supply the essential elements of a patented invention provided the defendant knows or it is obvious that the purpose of the supply is to infringe the patent (s. 60(2) PA 1977). A defendant may not replicate exactly what is claimed as the invention. The court must construe the claims in the light of the description and drawings in the patent to see whether the alleged infringement falls within the scope of the claims (Kirin Amgen (2004)). The Protocol to art. 69 EPC instructs its member courts to achieve a balance between fair protection for the patentee and certainty for third parties. Defences to infringement include private and non-commercial use, experimental use and prior use. Remedies for patent infringement include interim and final injunctions, damages or an account of profits, delivery up and destruction of infringing products and a declaration that the patent is valid. An action for patent infringement can only be started once the patent is granted but damages may be recoverable for infringements occurring in between publication of the application and grant. Infringement proceedings may be brought by the proprietor of the patent or an exclusive licensee. Groundless threats of patent infringement proceedings are actionable by the defendant (s. 70 PA 1977). A defendant to a patent infringement action will normally
argue by way of counterclaim that a patent is invalid.
Alternatively an application to revoke a patent can be made to
the comptroller or the court. Revocation
can only be ordered on the grounds that (s. 72 PA 1977):
There is no legal requirement for
patented products to be marked. However,
it is an offence to mark products as patented when no patent has been
granted. If a patent application has been
made the product can legitimately be marked "patent pending".
Marking a product serves as a warning to potential infringers. Provided the patent number accompanies the marking it can avoid an innocence defence to damages for infringement (s. 62 PA 1977). Community Patent A Commission proposal for a Community patent has been in
existence since 1973 but delayed by disagreements between Member States
over languages and jurisdictional issues (now, it seems, largely
resolved). Under the latest proposal an
applicant would apply for an EP designating the Community as a single
territory. The resulting EP granted by the
EPO would have unitary effect throughout the EU. The
Commission
has also proposed a unified patent litigation system, which
would deal with infringement and invalidity proceedings of both
European and future Community patents. The
new unified court structure would comprise a largely decentralised
court of first instance (with local and regional divisions), a single
court of appeal and a role of the ECJ aimed at providing a consistent
interpretation and application of Community law.
