SharpBrains’ Take:

The ‘995 patent applies EEG tech­nol­o­gy to mea­sur­ing a rel­e­vant fea­ture to every­one’s life: breath­ing. Specif­i­cal­ly, the res­pi­ra­to­ry mea­sure­ment cycle may be used to treat sleep-relat­ed breath­ing con­di­tions such as sleep apnea, hypop­nea and sleep frag­men­ta­tion. The dif­fer­ence in pow­er of the EEG sig­nal is used to cal­cu­late res­pi­ra­to­ry cycles at var­i­ous brain wave fre­quen­cies (e.g., alpha, delta, etc.) and used to infer breath­ing prob­lems or treat­ments to pro­mote health­i­er sleep­ing pat­terns. The ‘995 patent recites 40 claims with many of the depen­dent claims encom­pass­ing var­i­ous embod­i­ments towards mea­sur­ing and clas­si­fy­ing res­pi­ra­to­ry cycle fea­tures. Despite a poten­tial com­pet­i­tive design-around by using an EEG fea­ture oth­er than pow­er for cycli­cal res­pi­ra­to­ry assess­ments, the numer­ous and broad claim cov­er­age of an EEG appli­ca­tion to sleep and breath­ing result of the ‘995 patent result con­tribute its assess­ment as a key non-inva­sive neu­rotech­nol­o­gy patent.

Abstract:

A sys­tem and method for deter­min­ing res­pi­ra­to­ry cycle-relat­ed EEG changes (RCREC) for a sub­ject with sleep-dis­or­dered breath­ing are pro­vid­ed. The method includes receiv­ing an EEG sig­nal from the sub­ject using at least one sen­sor, and defin­ing at least two res­pi­ra­to­ry cycle seg­ments with­in each res­pi­ra­to­ry cycle. The method fur­ther includes deter­min­ing an EEG pow­er of the EEG sig­nal dur­ing each of the at least two res­pi­ra­to­ry cycle seg­ments, and deter­min­ing RCREC by cal­cu­lat­ing a dif­fer­ence between a max­i­mum EEG seg­ment pow­er and a min­i­mum EEG seg­ment power.

Illus­tra­tive Claim 38. A com­put­er read­able medi­um for deter­min­ing res­pi­ra­to­ry cycle-relat­ed EEG changes (RCREC) in a sub­ject, the medi­um comprising:

  • com­put­er read­able instruc­tions for deter­min­ing an EEG pow­er of a received EEG sig­nal for a plu­ral­i­ty of res­pi­ra­to­ry cycle seg­ments, and deter­min­ing RCREC by cal­cu­lat­ing a dif­fer­ence between a max­i­mum EEG seg­ment pow­er and a min­i­mum EEG seg­ment power.
