¹ If, as a res­ult of a par­tial sur­render, pat­ent claims re­main that may not ex­ist in the same pat­ent in ac­cord­ance with Art­icles 52 and 55, the pat­ent shall be lim­ited ac­cord­ingly.

² The pro­pri­et­or of the pat­ent may ap­ply for the is­sue of one or more new pat­ents to cov­er the dropped pat­ent claims; such new pat­ents are giv­en the fil­ing date of the ori­gin­al pat­ent.

³ Fol­low­ing re­gis­tra­tion of the par­tial sur­render in the Pat­ent Re­gister, the IPI shall set a time lim­it for the pro­pri­et­or of the pat­ent to ap­ply for the is­sue of new pat­ents in ac­cord­ance with para­graph 2; after this time lim­it has ex­pired, an ap­plic­a­tion is no longer ac­cep­ted.
