The theory associates to $(X,L)$ a $\mathbb {Z}$-graded chain complex of vector spaces over $\mathbb {Z}_2$, filtered with $k$ filtration levels. The corresponding $k$-level spectral sequence is invariant under deformations of $(X,L)$ and has the following property: if $(X,L)$ is obtained by joining a negative end of a pair $(X^{\prime },L^{\prime })$ to a positive end of a pair $(X^{\prime \prime },L^{\prime \prime })$, then there are natural morphisms from the spectral sequences of $(X^{\prime },L^{\prime })$ and of $(X^{\prime \prime },L^{\prime \prime })$ to the spectral sequence of $(X,L)$. As an application, we show that if $\Lambda \subset Y$ is a Legendrian submanifold of a contact manifold then the spectral sequences associated to $(Y\times \mathbb {R},\Lambda _k^s\times \mathbb {R})$, where $Y\times \mathbb {R}$ is the symplectization of $Y$ and where $\Lambda _k^s\subset Y$ is the Legendrian submanifold consisting of $s$ parallel copies of $\Lambda $ subdivided into $k$ subsets, give Legendrian isotopy invariants of $\Lambda $.
