Requesting Patent Information for ICODE SLIX2(SL2S2602) NFC Tag IC

[Hikari]

Hi NXP team,

I'm currently looking into ICODE SLIX2 NFC tag IC, and I'm particularly interested in how the STAY QUIET PERSISTENT command enables the tag's persistent time functionality on top of the ISO/IEC 15693 protocol. I believe reviewing the associated patents could provide valuable insights into the underlying circuit mechanisms.

However, I haven’t been able to locate the relevant patent numbers or documentation linked to this IC on the official product page. Could you please advise:

• Whether there are publicly available patents associated with this NFC tag IC

• Where I might find patent numbers or application references

• If there are any recommended resources or documentation that detail the circuit-level design

Thanks in advance for your help!
