Masking a private key/CERTICOM – T 0556/ 14 – 28 July 2016
In this decision in a patent a method of masking a privat key is claimed. It is considered not to be a mathematical method as such, because storing on a smartcard (hardware) was claimed. The claimed method achieves some protection against power analysis attacks and thus have a technical effect...
Koprozessor zur modularen Inversion/GIESECKE & DEVRIENT – T 2318/08 – 23. Mai 2012
This decision provides a known cryptographic coprocessor and a known Euclidean method. However, it is not known how to use free bit sections in the coprocessor to speed up the method. Therefore, the clever use of a known coprocessor to speed up the implementation of an equally known method solves...
Programmiersystem/RENNER – T 1539/09 – 18 July 2013
The invention is directed to a graphical programming language and environment that should enable a user to create programme code without a great deal of learning effort or special expertise.

Expert system/SCHINDLER – T 1817/ 14 – 4 July 2017
This decision concerns information modelling by a user to create a data structure, where this modelling has no technical effect. Therefore, the modelling steps are considered as an aim to be achieved in a non-technical field and used for the formulation of the technical problem (COMVIK II). The data structure...
