1. [Validity of Patent Not Affected by Non-Compliance with Certain Formal Requirements] Non-compliance with one or more of the formal requirements referred to in Articles 6(1), (2), (4) and (5) and 8(1) to (4) with respect to an application may not be a ground for revocation or invalidation of a patent, either totally or in part, except where the non-compliance with the formal requirement occurred as a result of a fraudulent intention.
2. [Opportunity to Make Observations, Amendments or Corrections in Case of Intended Revocation or Invalidation] A patent may not be revoked or invalidated, either totally or in part, without the owner being given the opportunity to make observations on the intended revocation or invalidation, and to make amendments and corrections where permitted under the applicable law, within a reasonable time limit.
3. [No Obligation for Special Procedures] Paragraphs 1 and 2 do not create any obligation to put in place judicial procedures for the enforcement of patent rights distinct from those for the enforcement of law in general.
