Proper construction of claim 1
Reformatio in peius (1st auxiliary request: no; 2nd and 3rd auxiliary request: inadmissible) - Catchword
- A claim was directed to a method for manufacturing a product. The method comprised manufacturing conditions the presence or absence of which during manufacture could not be ascertained in a reliable and generally accepted way but could only be derived from a property observed on the obtained product.
For the purpose of establishing whether a method disclosed in a prior art document anticipated the claimed method, the Board construed the feature relating to the manufacturing conditions as if it defined the property observed on the obtained product (point 3.1 of the reasons). - Cited cases
