Generate a 500-word article outlining a comprehensive guide to Intellectual Property (IP) protection.  The guide should cover various forms of IP (patents, trademarks, copyrights, trade secrets), their respective applications, registration processes, enforcement strategies, and common pitfalls to avoid.  The article should be targeted towards entrepreneurs and small business owners, using clear, concise language and avoiding overly technical jargon.  Include real-world examples of IP infringement and successful IP protection strategies.  The guide should also address international IP protection considerations and the importance of seeking professional legal advice when necessary.  Structure the article with clear headings and subheadings, making it easy to navigate and understand.  The final section should include a checklist of actionable steps for readers to take to protect their IP.  Success will be measured by the clarity, comprehensiveness, and practical applicability of the guide for a non-legal audience.
