REISSUE OF PATENTS 
47(1) Issue of new or amended patents 
47. (1) Whenever any patent is deemed defective or inoperative by reason of insufficient description 
and specification, or by reason of the patentee's claiming more or less than he had a right to claim 
as new, but at the same time it appears that the error arose from inadvertence, accident or mistake, 
without any fraudulent or deceptive intention, the Commissioner may, on the surrender of the patent 
within four years from its date and the payment of a further prescribed fee, cause a new patent, in 
accordance with an amended description and specification made by the patentee, to be issued to him 
for the same invention for the then unexpired term for which the original patent was granted. 
47(2) Effect of new patent 
(2) The surrender referred to in subsection (1) takes effect only on the issue of the new patent, and 
the new patent and the amended description and specification have the same effect in law, on the trial 
of any action thereafter commenced for any cause subsequently accruing, as if the amended description 
and specification had been originally filed in their corrected form before the issue of the original patent, 
but, in so far as the claims of the original and reissued patents are identical, the surrender does not 
affect any action pending at the time of reissue or abate any cause of action then existing, and the reissued 
patent to the extent that its claims are identical with the original patent constitutes a continuation thereof 
and has effect continuously from the date of the original patent. 
47(3) Separate patents for separate parts 
(3) The Commissioner may entertain separate applications and cause patents to be issued for distinct 
and separate parts of the invention patented, on payment of the fee for a reissue for each of the reissued 
patents. 
R.S., c. P-4, s. 50. 
DISCLAIMERS 
48(1) Patentee may disclaim anything included in patent by mistake 
48. (1) Whenever, by any mistake, accident or inadvertence, and without any wilful intent to defraud 
or mislead the public, a patentee has 
(a) made a specification too broad, claiming more than that of which the patentee or the person 
through whom the patentee claims was the inventor, or 
(b) in the specification, claimed that the patentee or the person through whom the patentee claims 
was the inventor of any material or substantial part of the invention patented of which the patentee 
was not the inventor, and to which the patentee had no lawful right, 
the patentee may, on payment of a prescribed fee, make a disclaimer of such parts as the patentee does 
not claim to hold by virtue of the patent or the assignment thereof

Page 33 
47. (1) Lorsqu'un brevet est juge defectueux ou inoperant a cause d'une description et specification 
insuffisante, ou parce que Ie brevete a revendique plus ou moins qu'il n'avait droit de revendiquer 
a titre d'invention nouvelle, mais qu'il apparait en meme temps que l'erreur a ete commise par 
inadvertance, accident ou meprise, sans intention de frauder ou de tromper, Ie commissaire peut, si 
Ie brevete abandonne ce brevet dans un delai de quatre ans a compter de la date du brevet, et apres 
acquittement d'une taxe reglementaire additionnelle, faire delivrer au brevete un nouveau brevet, 
conforme a une description et specification rectifiee par Ie brevete, pour la meme invention et pour 
la partie restant alors a courir de la periode pour laquelle Ie brevet original a ete accorde. 
47(2) Effet du nouveau brevet 
(2) Un tel abandon ne prend effet qu'au moment de la delivrance du nouveau brevet, et ce nouveau 
brevet, ainsi que la description et specification rectifiee, a Ie meme effet en droit, dans l'instruction 
de toute action engagee par la suite pour tout motif survenu subsequemment, que si cette description 
et specification rectifiee avait ete originalement deposee dans sa forme corrigee, avant la delivrance 
du brevet original. Dans la mesure OU les revendications du brevet original et du brevet redelivre sont 
identiques, un tel abandon n'atteint aucune instance pendante au moment de la redelivrance, ni n'annule 
aucun motif d'instance alors existant, et Ie brevet redelivre, dans la mesure ou ses revendications sont 
identiques a celles du brevet original, constitue une continuation du brevet original et est maintenu 
en vigueur sans interruption depuis la date du brevet original. 
47(3) Brevets distincts pour elements distincts 
(3) Le commissaire peut accueillir des demandes distinctes et faire delivrer des brevets pour des elements 
distincts et separes de l'invention brevetee, sur versement de la taxe a payer pour la redelivrance de 
chacun de ces brevets redelivres.

et sans intention de frauder ou tromper Ie public, dans l'un ou I'autre des cas suivants : 
a) il a donne trop d'etendue a son memoire descriptif, en revendiquant plus que la chose dont 
lui-meme, ou son mandataire, est l'inventeur; 
b) il s'est represente dans Ie memoire descriptif, ou a represente son mandataire, comme etant 
I'inventeur d'un element materiel ou substantiel de I'invention brevetee, alors qu'il n'en etait pas 
I'inventeur et qu'il n'y avait aucun droit

suite, reputee faire partie du memoire descriptif original. 
48(4) Sans effet sur les actions pendantes 
(4) Dans toute action pendante au moment ou elle est faite, aucune renonciation n'a d'effet, sauf a 
l'egard de la negligence ou du retard inexcusable a la faire. 
48(5) Deces du brevete 
(5) Si Ie brevete original meurt, ou s'il cede son brevet, la faculte qu'il avait de faire une renonciation 
passe a ses representants legaux, et chacun d'eux peut exercer cette faculte. 
48(6) Effet de la renonciation 
(6) Apres la renonciation, Ie brevet est considere comme valide quant a tel element materiel et substantiel 
de l'invention, nettement distinct des autres elements de l'invention qui avaient ete indfunent revendiques, 
auquel il n'a pas ete renonce et qui constitue veritablement l'invention de I'auteur de la renonciation, 
et celui-ci est admis a soutenir en consequence une action ou poursuite a l'egard de cet element.
