What exactly is a patent?

A patent is a grant of exclusive commercial right to exploit and authorise others to exploit an invention for the duration of the patent.  In Australia, a patent can be granted for a new, useful and inventive or innovative:

• product, such as a machine, device or substance; and/or
• process or method.

When is a patent infringed?

To establish infringement the Patent owner (or an exclusive licensee) must prove that the product which is alleged to infringe takes all of the essential integers of the claims of the Patent (see Doric Products Pty Limited v Asia pacific Trading (Aust) Pty Ltd [2017] FCA 849 at [38]).  The Court in Doric said at [38]:

“As a fundamental rule, the test for infringement is determined by the construction of the claim, and there will be no infringement unless the alleged infringer has taken all of the essential features of the claim”.

What are the essential integers of the claims of a patent?

Whether an integer is “essential” or not is generally determined by the patentee (Fresenius Medical Care Australia Pty Limited v Gambro Pty Limited [2005] FCAFC 220 at [45]).  An integer will usually be essential unless it does not materially affect the way the invention works.  Even if a feature does not materially affect the way the invention works, an integer is essential if it is evident from reading the patent that the feature is intended to be essential (Catnic Components v Hill & Smith Ltd (1982) RPC 183).

Cross claiming to revoke a patent

When faced with allegations of infringement as well as considering whether the respondents product takes all of the essential integers of the patent in suite its usual to consider the grounds of which the patent could be revoked for reasons of invalidity.  The basis that any patent could be revoked is the opposite of the reasons it should have been granted in the first place.  Put another way a patent could be held to be invalid because:

• it lacks of novelty (section 7(1) and section 18) (Lack of Novelty);
• it lacks an inventive step (section 7(1) and section 18) (standard patent) (Inventive Step);
• it lacks of innovative step (section 7(1) and section 18) (innovation patent) (Innovative Step);
• the invention is not useful (section 18(1)(c)) (Usefulness);
• the invention was secretly used in the patent area before the priority date of the claim (section 18(1)(d)) (Secret Use);
• is not a manner of manufacture within the meaning of section 6 of the Statute of Monopolies (section 18(1)(a)) (Manner of Manufacture); or
• other grounds for invalidity:
  • patent obtained by fraud, false suggestion or misrepresentation (section 138(3)(d)) (Fraud, False Suggestion or Misrepresentation);
  • the patent specification does not provide sufficient information and instruction for a person skilled in the field that the patent relates to be able to perform the teaching of the patent and produce an invention falling within the claims of the patent (section 40(2)(a)) (Sufficiency);
  • failure to disclose the best method known to the patent applicant of performing the invention (section 40(2)(aa)) (Best Method); or
  • the claim or claims must be clear and succinct and supported by matter disclosed in the specification (section 40(3)) (Fair Basis).

There are of course other grounds for revoking a patent, which could apply on case-by-case basis, however the above are the generally accepted categories.
