Yes, of course. Patterns are discovered all the time. Like living beings, some mutate and form new patterns, for instance, MVC variants such as Model-view-presenter (MVP), Hierarchical model-view-controller (HMVC), or Model View ViewModel (MVVM).

Patterns also evolve with time, as better solutions to known problems are identified. For example, Singleton pattern was once considered to be a design pattern but now is considered to be an anti-pattern due to the shared state it introduces, similar to using global variables. An anti-pattern can be defined as a commonly reinvented but a bad solution to a problem. Some of the other well-known books that catalog patterns are Pattern-oriented software architecture (POSA) by Buschmann, Meunier, Rohnert, Sommerlad, and Sta; Enterprise Integration Patterns by Hohpe and Woolf; and The Design of Sites: Patterns, Principles, and Processes for Crafting a Customer-Centered Web Experience by Duyne, Landay, and Hong.
