How can I protect myself from having a patent infringed?

If your patent is infringed you can institute injunction proceedings with Vienna Commercial Court. You can also demand that the objects infringing the patent or the tools and equipment used to manufacture them are destroyed or relinquished to you (§148 PatG). You can apply for publication of the ruling (§ 149 PatG) as well as pursue financial claims (compensation, surrendering of profits, damages, §150ff. PatG).
