ISAZISO ESIBALULEKILE FUNDA NGOKUQAPHELA I-STMicroelectronics NV kanye nezinkampani ezingaphansi kwayo (“ST”) igodla ilungelo lokwenza izinguquko, ukulungisa, izithuthukisi, izinguquko, nokuthuthukiswa kwemikhiqizo ye-ST kanye/noma kule dokhumenti nganoma yisiphi isikhathi ngaphandle kwesaziso. Abathengi kufanele bathole ulwazi lwakamuva olufanele ngemikhiqizo ye-ST ngaphambi kokufaka ama-oda. Imikhiqizo ye-ST ithengiswa ngokulandela imigomo nemibandela ye-ST yokuthengisa ekhona ngesikhathi sokuvunywa kwe-oda. Abathengi banomthwalo wemfanelo kuphela ekukhetheni, ekukhethweni, nasekusetshenzisweni kwemikhiqizo ye-ST futhi i-ST ayithathi sikweletu sosizo lwesicelo noma idizayini yemikhiqizo yabathengi. Ayikho ilayisensi, eshiwo noma eshiwoyo, kunoma yiliphi ilungelo lempahla yengqondo elinikezwa i-ST lapha. Ukudayiswa kabusha kwemikhiqizo ye-ST nezinhlinzeko ezihlukile kulwazi olubekwe lapha kuzovala noma yisiphi isiqinisekiso esinikezwe i-ST salowo mkhiqizo. Ilogo ye-ST kanye ne-ST yizimpawu zokuthengisa ze-ST. Ukuze uthole ulwazi olwengeziwe mayelana nezimpawu zokuthengisa ze-ST, bheka ku-www.st.com/trademarks. Wonke amanye amagama omkhiqizo noma wesevisi ayimpahla yabanikazi abafanele. Ulwazi olukule dokhumenti luthatha indawo futhi luthatha indawo yolwazi olwalunikezwe ngaphambilini kunoma yiziphi izinguqulo zangaphambili zalo mbhalo.
