Federal Act
on Patents for Inventions
(Patents Act, PatA)¹

¹ The pae­di­at­ric cer­ti­fic­ate is null and void when:

a.

it is is­sued in con­tra­ven­tion of Art­icle 140t or if it sub­sequently con­tra­venes Art­icle 140t;

b.

it is is­sued in con­tra­ven­tion of Art­icle 140u para­graph 2;

c.

the pat­ent lapses be­fore the end of its max­im­um term (Art. 15);

d.

the pat­ent is found to be null and void;

e.

the pat­ent is lim­ited to such an ex­tent that its claims no longer cov­er the product for which the pae­di­at­ric cer­ti­fic­ate was gran­ted;

f.

after the pat­ent has lapsed, there are grounds which would have jus­ti­fied a de­clar­a­tion of nullity un­der let­ter d or a lim­it­a­tion un­der let­ter e.

² Any per­son may bring an ac­tion for the pae­di­at­ric cer­ti­fic­ate to be de­clared null and void be­fore the au­thor­ity com­pet­ent to de­clare the pat­ent null and void.
