Northwestern was elected to the Association of American Universities in 1917 and remains a research university with "very high" research activity. Northwestern's schools of management, engineering, and communication are among the most academically productive in the nation. Northwestern received $550 million in research funding in 2014. Northwestern supports nearly 1,500 research laboratories across two campuses, predominately in the medical and biological sciences. Through the Innovation and New Ventures Office (INVO), Northwestern researchers disclosed 247 inventions, filed 270 patents applications, received 81 foreign and US patents, started 12 companies, and generated $79.8 million in licensing revenue in 2013. The bulk of revenue has come from a patent on pregabalin, a synthesized organic molecule discovered by chemistry professor Richard Silverman, which ultimately was marketed as Lyrica, a drug sold by Pfizer, to combat epilepsy, neuropathic pain, and fibromyalgia. INVO has been involved in creating a number of centers, including the Center for Developmental Therapeutics (CDT) and the Center for Device Development (CD2). It has also helped form over 50 Northwestern startup companies based on Northwestern technologies.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many companies were started through Northwestern's Innovations and New Ventures Office?<|im_end|>

Based on the information provided, 12 companies were started through Northwestern's Innovation and New Ventures Office (INVO).<|im_end|>

 Based on the information provided in the text, the answer to your question is:

12 companies were started through Northwestern's Innovation and New Ventures Office (INVO).

Here's my step-by-step reasoning:

1. According to the text, INVO was involved in creating "over 50 Northwestern startup companies based on Northwestern technologies."
2. However, the text also states that 12 companies were started through INVO.
3. Therefore, we can deduce that the number of companies started through INVO is 12, which is a subset of the total number of startup companies based on Northwestern technologies.

Justification:

The text provides specific information about the number of companies started through INVO, which is 12. It also provides a broader estimate of the total number of startup companies based on Northwestern technologies, which is over 50. By comparing these two pieces of information, we can determine the number of companies started through INVO.<|im_end|>
