A fourteen-page Patent Act study note that outlines the forms of patent infringement and the remedies available to a patent holder when infringement occurs. Because it pairs statutory provisions with their meaning, it is useful for exam preparation or for outlining an assignment. The first part covers direct and indirect infringement. It defines direct infringement, working a patented invention without authority, separately for product inventions, process inventions and inventions of a process for producing a product, and summarizes six types: literal infringement and infringement under the doctrine of equivalents, utilization and conflict infringement, incomplete-use infringement, selection infringement and detour infringement.

For indirect infringement it covers the purpose and requirements, how the 'used only for producing' requirement is interpreted, and the relationship with direct infringement. The second part deals with remedies. It first explains special provisions such as presumptions of negligence and of the production process, presumptions of the amount of damages and document production orders, then summarizes civil remedies: injunctions and preventive claims, damages claims and the rules for calculating damages, claims to restore reputation, claims for restitution of unjust enrichment, and warnings and preservation of evidence.

It then covers criminal remedies such as the offenses of infringement, perjury, false marking and violating a confidentiality order, as well as administrative fines and resolution through settlement, arbitration and mediation, showing ways to resolve disputes outside court as well. Whenever I saw a patent number printed on household product packaging, I wondered what exactly was protected. Through this note I learned that even for the same product there are several routes to finding infringement, such as literal infringement and the doctrine of equivalents.

The section that splits the damages-presumption provisions into text and meaning shows, in reverse, how hard it is for a patent holder to prove loss. It is long, but the tight numbering lets you find the item you need right away. Passages comparing it with other claims, such as on extinctive prescription, also help prevent mistakes. The criminal section mixes in pre-amendment content, so I recommend checking it against the current Patent Act.
