Thaty may not be necessary since our patents are now declared valid....only case that would be sought in Germany would be a company who claims simple non-infringement...but if that were the case, IMO, that would have been the court actions we would have seen rather than someone fighting the validity of the patents.
Of course the big infringers could easily choose to go to court on simple non-infringement esp. if the dollars we would be asking for were of a very high value...then the legal cost would be worth the fight and also the delay it would impose on us..esp with the cash we need to keep this company on an even keel.
