An invention is patentable only if it is:
Computer software on its own can be protected by copyright but not by patents in Europe. However, an invention that is implemented on computers by means of software - for example, an improved data handling system - is patentable in Europe. You will certainly need the advice of a patent attorney when patenting inventions which are run on computers because practice can differ between Europe and the USA.
Business methods may be patentable in the USA but not easily patentable elsewhere.
Always seek advice from a patent attorney if you have concerns about whether your idea is patentable.

Applying for a patent is a legal process governed by strict timescales and usually immovable deadlines. It is not something to rush into! To maximise your chances of a worthwhile patent you should:
Here is only a very brief guide to the application process for a European Patent according to the European Patent Convention (EPC).
Applying for a patent at a national IP office is roughly similar to stages 1-6 below, but an application must be made in the local language.
Making an international application through the Patent Co-operation Treaty (PCT) involves a single procedure for stages 1-4, but 30 months after filing the application goes through stages 5 and 6 in every national or regional IP office where you wish to take up protection. For more information on the PCT see www.wipo.int/pct .
Choosing your route for a patent application (EPC, PCT, national and regional, or combinations thereof) will depend on:
A patent attorney will be able to advise you on the route that is best for you and your invention.
Your patent attorney must provide documentation consisting of:
A fee must also be paid. In order to avoid delay, it is vital that all documentation conforms in every detail to official requirements. Your patent attorney will ensure that it does. At the EPO, applications are accepted in English, French or German.
For your patent attorney to prepare all the information about your invention, he or she will obviously need to work closely with you. Do not assume that you know best because it is your invention. You must trust the skill and judgement of your patent attorney, as patenting involves a complex mix of law and technology. The claims in particular need to be drafted with skill, as they are the most important aspect of a patent.
If your documentation appears correct, your application is given a filing date - also known as your priority date. After filing there is a formalities examination to ensure that your documentation is correct and complete.
At any time in the next 12 months you can file for patent protection in other countries and have those later filings treated as if they had been filed on your priority date. In practice, this gives you a year to decide how many countries you wish to include in your patent protection.
A search report is sent to you, listing and including copies of all prior art documents found by an experienced examiner and regarded as relevant to your invention. The search is based mainly on your claims for novelty, but your description and any drawings will also be taken into account. The report will often include an initial opinion on the patentability of your invention.
Your application is published 18 months after the filing date. Your invention will appear in databases accessible to other people around the world. It will act as prior art against any future patent applications from other inventors or companies for similar inventions.
You then have six further months to make two decisions:
After your patent is granted, you may claim damages for infringements originating as far back as the publication date of your application. However, to enjoy this right in some countries it may be necessary to file a translation of your claims with their national IP office and for them to publish the translated claims.
If you request substantive examination, the EPO has to decide whether your invention and your application meet the requirements of the European Patent Convention. For maximum objectivity there are usually three EPO examiners, one of whom maintains contact with your patent attorney. This stage will often involve dialogue between the examiners and your patent attorney, which may result in the re-drafting of key parts of your application. Your patent attorney will defend your application, and this is one more reason why it is essential to have professional representation.
If the examiners decide to grant a patent, and all fees have been paid and any claims translations filed, the decision is reported in the European Patent Bulletin. The decision to grant takes effect on the date of publication.
What you have now got is a ‘bundle' of individual national patents. After the EPO decision to grant is published, your patent has to be validated in each designated state within a specific time limit. If this is not done, your patent may not be enforceable in that state. In some states, validation may include having to file (and pay for) a translation of the whole patent, or just a translation of the granted claims.
A granted patent may be opposed by third parties - usually the applicant's competitors - if they believe it should not have been granted. After the grant is reported in the European Patent Bulletin they have nine months in which to file notice of opposition. The most common charge is that the invention is not novel or lacks an inventive step. The case will be examined by an EPO team, again of three examiners.
Opposition is the last chance to attack a European patent as a single entity in a single forum. Later, the patent can only be challenged in national courts and a ruling in one country has no effect on the patents for the same invention in other countries. This gives competitors a strong incentive to challenge an invention during the opposition period, as challenging patents in separate national courts can be much more expensive.
All EPO decisions are open to appeal. Responsibility for decisions on appeals is taken by independent boards of appeal.
