Patent vs Design: Kya Farq Hain?

Yaar samajh nahi aaya. Mera concept test ke liye kuch questions aaye hain aur usmein patent aur design ke farq ka concept aaya hai. Problem yeh hai ki in dono ka concept ek dhoondh-paath ka lagata hai. Yeh hai kya ki ek invention ki raksha karte samay hum patent apply karte hain, lekin jab woh invention apne vishisht design ke liye jaani jaati hai, toh hum design registration ki baat karte hain.

Toh yeh question aaya ki, patent aur design ki kya baat hai? Agar ek invention ka design bahut hi vishisht hai aur hum uske liye jaani jaana chahte hain, toh hum kya registration karte hain?
