The LPO derives its roots from KPO (Knowledge Process Outsourcing). KPO refers to knowledge-intensive work that involves
specialized domain expertise. High value processes that fall into this realm include: valuation research, investment research, patent filing and legal and insurance
claim analysis. LPO in India started as a low-end work that mainly included transcription. But now LPO in India is a high-end knowledge intensive work. Presently everything
from patent application drafting, legal research, pre-litigation documentation, advising clients, analyzing drafted documents, writing software licensing agreements to drafting
distribution agreement is being outsourced to India. This potential growth took place to such an extent that today patent filing has its own separate existence different from LPO
referred to as Patent Process Outsourcing (PPO).
