Content includes: comprehensive presentation of the case law of the Federal Court of Justice (BGH); even greater consideration of the case law of the lower courts; complete incorporation of the accessible practices of the Arbitration Board for Employee Inventions at the DPMA; documentation of relevant literature; recent legal developments: new definition of the employment contract in Section 611a of the German Civil Code (BGB), planned introduction of the EU unitary patent. Key topics of the 6th edition include, among others: international aspects, research and development collaborations, developments within corporate groups and their remuneration, co-inventorship in employee inventions and its implications, due dates, amounts, regulation, and limitation periods for remuneration.
