“Inthecircumstances,itisratherdifficulttotellexactlywherewe

theproblemintotwoquestions:first,whetherwhattheGuertinsdidwas

AfterreviewingtheBritishauthoritiesandconcludingthatitisnotan

Inthatcase,thepatentsprotectedthecombinationofpreformedarmourrods
withastrandedelectricpowertransmissionline.Theplaintiffshadnoprotection

manufacturingthepreformedarmourrodsandsellingthemtothepower

agreedthatthedefendantsknewthatthepreformedarmourrodscouldbe

Thiscaseillustrateswhytheprimaryinfringeroftenisnotsued.Thefollowingisan

“Theproblemofplottingthelinebetweeninfringementandnon-
infringementinthesecircumstancesarisesbecausethepatenteeis
oftenreluctanttosuetheprimaryinfringerwhousesthe
combinationinthatsuchuserisagoodcustomerofthepatentee.”
TheCourtreviewedthesituationintheUnitedStatesandinEngland,and
acceptingtheCopeland-Chattersoncaseasbeingthelawunderthepresent
CanadianPatentAct,itstatedtheproblemasfollows:
“ThequestionthatIhavetodecideis,therefore,whetherthe
defendantinthiscase”knowingly”,andforhisownendsand
benefitandtothedamageofthepatentee,hasinducedor
procuredanotherto”infringe”theplaintiffs’patent.”
Thefollowingelementshadtobeproven:

a)actualinfringementbyapurchaser(therecannothavebeen

infringement);
b)wasthispurchaserinducedorprocuredtoinfringebythedefendants;
c)ifthispurchaserwasinducedorprocuredbythedefendants,didthe
defendantsdosoknowingly.
Forthepurposeoftheargument,theCourtassumedthatactualinfringement
hadbeenestablished.Turningtothesecondaspect,theCourtsaid:
(p.87)
Inconsideringwhetherwhatthepowerentitiesdid(whichforpresent
purposesIshallassumewasa”wrongfulact”)wasinducedorprocuredby
thedefendants,itmustbeborneinmindthatwhatwearetalkingaboutis

consideringthisaspectofthematter,thatthedefendantscaninnoway
beheldresponsibleforthefactthatthepowerentitiesmadethe
combinationcoveredbythepatentinsuit.Itwasbeingused,
presumablywiththeactiveinvitationofthepatentee,since1953,and
thereforelongbeforethedefendantcompanycommencedoperations
in1963.Whatthedefendantsmustbefoundtohaveinducedor
procured,iftheplaintiffsaretosucceed,isthemakingofthepatented
combinationbythepowerentitieswithoutalicencefromthepatentee.

1)Thattherespondenthadsoldassembledboards;
2)Thatanyonewasinducedbytherespondenttoassemblethesailboardin

(p.264)
