My opinion is learning design patterns are very important to being a really good programmer. Patterns (and Anti-patterns) are an extremely useful part of software development, specifically because they help engineers be more efficient at solving problems with code. Factory, funny enough, is the name of a design pattern. And for good measure, DRY Violation is a good anti-pattern to pick up (though I suspect you know that already even if you can't name it).
