Cautions when Filing in Canada

(1) Double Patenting;

(2) Subject Matter prohibitions (for example, higher life forms, embryos, totipotent stem cells, antibodies, organs, tissues, artificial organ-like or tissue-like structures, methods of medical treatment, dosage ranges and dosage regimes);

(3) typical patent firms;

(4)          no late entry; and

(5)          excess claims fees payable based on the greatest number of claims pending between the Examination Request and Issue Fees payment.
