TRANSCRIPT
An invention is only patentablewhen it is novel and not obviousover what others have inventedbefore, called the “prior art.”Creating prior art citable against acompetitor’s patent applicationsby filing your own patentapplication can prevent thecompetitor from obtaining apatent, or the full protection itdesires. The U.S. Patent Office’sinterpretation of changes in U.S.patent law made by the AmericanInventors Protection Act of 1999(“AIPA”) provides a way to createprior art with an earlier effectivedate, and may be of particularinterest for those filing in the U.S.based on a foreign or PatentCooperation Treaty (“PCT”)application.
An applicant’s goal is to achieve theearliest possible date at which theapplication will stand as prior art. Ifclaiming priority to a foreign or aPCT application, an applicant canaccomplish this goal by filing a 35U.S.C. § 111(a) application in theU.S. When a PCT applicationprovides the basis for a U.S. filing,the PCT filing should be in Englishand designate the U.S. Although thisseems to be fairly simple, priorityand prior art are complex areas of
patent law. For more specificinformation or questions aboutusing one’s own patent application tocreate the best prior art position, apatent applicant should consult apatent attorney.
Generally, in pursuing patentprotection, it is best to obtain theearliest possible filing date. Theearlier an application is filed, thesooner it should issue as a patent.Secondly, filing as soon as possiblemay create prior art to prevent acompetitor from obtaining a patent,or may narrow the scope of acompetitor’s patent. One reason isthat the U.S. Patent Office views theU.S. filing date as the constructivedate of invention.
To obtain a U.S. patent, an inventormust be the first inventor. Inaddition, other statutes addresssituations where patent rights maybe lost even though an inventor mayhave been the first to invent.
A U.S. patent application may bebased on an earlier filed foreignpatent application or PCTapplication. The actual U.S.application may be filed as a nationalapplication under § 111(a), claimingpriority to a foreign filing or PCTapplication, or the U.S. application
may be filed as a national stageapplication under § 371, claimingpriority to a PCT application. TheAIPA changed the prior art effectgiven to § 111(a) and § 371applications and patents issuing fromsuch applications.
Prior to the enactment of the AIPA,U.S. law provided that a patentissuing from a § 111(a) applicationbecame a prior art reference againstanother pending application as ofthe date the application was filed inthe U.S. If the same patent issuedfrom a PCT national stageapplication filed under 35 U.S.C. § 371, then the patent became aprior art reference as of the datewhen the national stagerequirements were fulfilled with theU.S. Patent Office, which could bemonths after the date ofcommencement of the U.S. nationalstage.
For a U.S. patent application filed onor after November 29, 2000, theAIPA provides that, in most cases,the application will publish 18months after being filed. Because apending U.S. patent application maynow become available to the public,U.S. law was changed to identifywhen pending applications andpatents will be prior art references

against another inventor’sapplication.
Applicants’ understanding of thechanges is still evolving, but thePatent Office has interpreted thechanges1. This interpretation mayprovide a competitive edge byshowing an applicant how toestablish the earliest prior art date tobe cited against a competitor alsoseeking a patent.
Generally, an application with aforeign priority claim has three pathsto enter the U.S. patent system:
1. Start with a complying2 PCTapplication, i.e., a PCTapplication in English anddesignating the U.S.
2. Start with a non-complying PCTapplication, i.e., a PCTapplication in a language otherthan English or not designatingthe U.S.
3. Enter the U.S. within one yearfrom the earliest foreign priorityfiling date.
An example of each of these threefiling paths is represented andnumbered On the following page.The paths show the dates when theapplication or resulting patent will
be a prior art reference againstanother application or patent3. Inpaths 1 and 2, the applicant has thestrategy choice of proceeding with a§ 111(a) application, path 1a and2a, (claiming priority to the firstfiled foreign application or a PCTapplication) or a § 371 application,path 1b and 2b, (claiming priority toa PCT application). In path 3, theapplicant proceeds with a § 111(a)application (claiming priority to thefirst filed foreign application).
From these scenarios, it is apparentthat the Patent Office is no longergiving prior art effect to patentsissuing from § 371 applications and,in some circumstances, to § 371applications. Therefore, for anapplication and a patent to become aprior art reference against anotherapplication as early as possible, theU.S. application should be filedunder § 111(a). If the PCT is used,then the PCT application should bein English and designate the U.S.Two exemplary recommendedprocedures for establishing the priorart position most likely to affectcompetitors’ applications follow:
• File a provisional application in theU.S. as soon as possible.Provisional applications do notneed to be in English, so a U.S.
provisional could be filed at thesame time as, or shortly after, theforeign priority application is filed.Then, within one year, file a U.S.non-provisional application under§ 111(a), claiming priority to theprovisional, and provide an Englishtranslation of the provisional.Under this procedure, the prior artdate for the U.S. application andthe resulting patent should be thefiling date of the provisionalapplication.
• File a PCT application in Englishdesignating the U.S. and thenenter the U.S. by filing a § 111(a)application on or before the PCTdeadline. This way, the prior artdate for the U.S. application willbe the filing date of the complyingPCT. However, the prior art datefor the patent will be the date the §111(a) application was filed (or, ifapplicable, the date a U.S.provisional application was filed).
1 Manual of Patent Examining Procedure,Sec. 1896 “Effective Date as a Reference”(8th Ed. Aug. 2001).
2 As used herein, complying or non-complying does not refer to the validity orviability of a PCT application.
3 When there is a printed publication, such asa PCT publication, then the publicationwill be a reference against another’sapplication as of the date of the publication.
