Questão jurídica principal
Whether amended patent CH 333.________ was partially invalid because the amendment added subject matter beyond the original application
Decisão extraída
Yes. The amended claim went beyond the original disclosure, so the patent was partially null to that extent.
Fundamentação extraída
Under the old and current patent rules, an amendment is impermissible if the skilled person cannot directly and unambiguously derive the replaced or broadened feature from the original filing. The deleted rotary-lagering feature was presented as essential in the original disclosure, so its removal broadened the claim unlawfully.
