Innovate core experience
Instead of innovating everything in a product, focus on innovating the core experience and use design patterns for rest of the product.
User experience design is not just about creativity. However, some people tend to innovate everything and add too many features in a product. Such products often fail to be usable since too many innovations lead to a steep learning curve. Users would take a lot of time in understanding several new interaction paradigms. Instead, focus on identifying the core experience/ differentiator that will be used 80% of the times and then spend most of your time innovating and polishing this core experience. For the rest of the design, primarily apply design patterns for an overall usable, yet innovative experience.
For some enterprise applications, the core experience would be the dashboard and its drill down pages. You may spend most of your time innovating the dashboard and the drill downs. For the rest of the application, such as login, account settings, profile etc. you can use design patterns.
