Case brief

All challenged claims cancelled

The Board cancelled all fifteen claims of SCA's interfolded-napkin patent - on art from 1919 - and the Federal Circuit affirmed.[12][8][25]

The '443 patent issues September 25, 2012·Cascades petitions for review of claims 1-15 September 29, 2017·Board institutes - but not on every asserted ground March 27, 2018·After SAS, institution expands to all claims on all grounds April 27, 2018·Oral hearing before the Board December 14, 2018·Final written decision: all 15 claims unpatentable February 25, 2019·Federal Circuit affirms, nonprecedential May 8, 2020

  • The '443 patent covers a stack of interfolded absorbent sheets - embossed paper napkins for dispensers.[7][27]
  • The petition stacked obviousness grounds on vintage folding patents and a napkin standard - and after SAS, every ground went to trial.[8][9][10][3]
  • The Board found the combinations predictable: century-old folding patents plus the industry standard added up to every claim.[11][18]
  • Essity appealed, and the Federal Circuit affirmed in a nonprecedential opinion.[17][16][25]

Two durable lessons: SAS ended partial institution, and old art is not weak art.[3][4][21]
