Nike's loss of this patent in the IPR and on appeal reduces its ability to block or extract royalties from Lululemon. Watch for Lululemon's stock reaction (bullish for LULU) and any subsequent IPR filings by Nike on related patents. The nonprecedential nature limits broader industry impact, but the specific competitive dynamic is now shifted.
