Patent-intensive enterprises and enterprises with core technology mastery are not suitable for open innovation.
1. Patent-intensive enterprises: Patent-intensive enterprises usually protect their technology and intellectual property rights through patents and limit the use and contact of outsiders, so they are not suitable for open innovation.
2. Enterprises with core technology mastery: Enterprises with core technology mastery usually have unique technologies and intellectual property rights, but are unwilling to share them with outsiders, so they are not suitable for open innovation.
