Short answer. Yes. Article 722 of the Civil Code states that the scientist or technologist has ownership of their discovery or invention even before it is patented. A patent is not the source of the inventor's ownership — it formalizes and strengthens rights that already exist at the moment of creation.
What the law says
The scientist or technologist has the ownership of his discovery or invention even before it is patented.

Ownership before a patent is filed
Scientists, engineers, and inventors often believe they own nothing until they hold a patent certificate. Article 722 establishes the opposite principle: the Civil Code treats a scientist or technologist as the owner of their discovery or invention from the moment it is made, not from the moment a government office issues a patent. The same article applies this rule consistently across creative categories — authors before publication, artists before copyright registration, scientists before patent grant. In each case, the creation event, not the formality, is the source of ownership.
What a patent does, then, if ownership already exists
A patent does not create ownership — it publicizes and enforces it. Under the Intellectual Property Code of the Philippines (Republic Act 8293), a patent gives the holder the exclusive right to exploit the invention commercially, to prevent others from making, using, selling, or importing it without permission, and to license the rights to others. Without a patent, the inventor owns the invention but has limited ability to stop others from using it — particularly if someone independently arrives at the same invention and files a patent first. This is why patent filing, while not the origin of ownership, is practically critical.
The race to the patent office matters
Philippine patent law generally follows a first-to-file system, not a first-to-invent system. This means that even if you were the original inventor, someone who files a patent application before you could obtain rights to the invention — effectively cutting you off from commercial exploitation. Article 722 establishes your underlying ownership, but that ownership, without the patent, may be difficult to enforce in a commercial context. The pre-patent period is the window when your ownership is most vulnerable. Documenting the invention meticulously, with dated records and evidence of the development process, helps protect your position during that window.
Employer-owned inventions are a different question
Article 722's rule about ownership applies to inventors in their personal capacity. When an invention is made by an employee in the course of their employment, particularly using the employer's resources and time, different rules under the Intellectual Property Code may assign ownership to the employer rather than the individual employee. The Civil Code's recognition of pre-patent ownership does not override employment contracts or IP Code provisions that allocate inventions made on company time to the company. If you invented something at work, whether it is yours or your employer's depends on your contract and the circumstances of the invention.
