Microsoft keeps taking my ideas, seriously!

Well they can access it from outside of their campus and steal it again. Is there any copyright policy? Can you sue them?

How big companies handle this situation?

OP: Instead of whining, you better get the internet on the case. Meaning, try it by social media: round up all the twitter and FB followers of yourself, your team members, friends etc. Craft a blog post complete with timelines, screenshots, etc that shows MSFT's guilt. Aside from your network, do extensive search of people with large# of followers (prioritized by those with an interest in your space) and contact all of them with your story and 1 request: to mention it to their crowd and if tweeting, to @mention MSFT, Satya too. If you have to, pay where applicable. Contact all relevant press and bloggers too and if they're on it, they will ask MSFT, Satya for comment. For perfect storm, pick a date and time then tell your network to please blog/post/tweet then to increase chances of virality. Then let the internet do its work.

You're welcome.

Change your name. Go to a foreign country, the most exotic you can find. Then live a normal life far from Microsoft stealing your ideas. Seriously!

Before that, you may try something: imagine, develop, and launch a product which contains a bomb inside. A bomb you alone can stop. If MS steal it, they will suffer of that and the world will know they stole your IP.

But do not sue them. It's pointless. You can't win, or if you can win, it would take so much time you will die one century before trial.

Just go back to work for them. Next problem ?

If like you say they copied you word for word why don't you just out them publicly? I'm sensing you're pulling a fast one on us.

If Microsoft is releasing the exact same thing, right after you do, I'd look seriously into whether they're outright copying, or perhaps an employee is leaking your work. Or maybe outright industrial sabotage.

Another alternative is to see if you can parlay this amazing capability into a job at Google: chief Microsoft next app predictor. Tongue in cheek, but with a serious core.

Boeing did the same thing to me. I was building my own 787 right as they released theirs (sarcasm). I sense bullshit with this post. Why wouldn't you expose them publicly especially if it wasn't a one-time occurrence?
